What kind of glue to glue cardboard to cardboard and other materials. How to glue a tree and what kind of glue is better Stickering thin paper on plywood

Lovers of needlework and creativity often face the choice of the most suitable glue. Their choice on the market is very large, so when buying, you need to consider what material you have to work with.

For different techniques handicrafts, one or another option is most preferred. Some, for example, PVA, are universal and are suitable for gluing several materials popular among craftsmen at once.

1. PVA - the best choice for paper, plastic, fabric and foam. Also this best option for those who are going to crafts from threads and glue.
2. Hot glue is the best choice for making crafts with fabric, glass, ceramic, wood, paper, plastic, foam.
3. For a tree - the name speaks for itself. Only suitable for wood parts.
4. Aerosol - well fastens paper, fabric, foam, plastic, organics.
5. Superglue - although the manufacturer calls it universal and promises reliable bonding of almost all materials, in practice it is worth using it with glass, ceramics, metal, plastic, organics.
6. Rubber - despite the name, it is suitable for gluing wood, fabric, paper, foam.
7. Silicone - bonds plastic, glass, metal and ceramics.
8. Epoxy - suitable for glass, ceramics, wood, plastic, metal and organics.
9. Polyurethane glue holds wood, plastic, ceramics, metal, organics together.

And the glue gun for crafts is also very convenient to use.

It is non-toxic, does not have an unpleasant odor, and securely and quickly fastens parts.

He also:

• spends sparingly
• easy to use, even children can handle it,
• securely fastens parts,
• the seam is not afraid of moisture,
• The adhesive fills the voids and seals well.

Silicone glue appeared on the domestic market recently, but quickly gained popularity. It is used for building and finishing works as well as arts and crafts.

Today, manufacturers offer two types of formulations - neutral and acetic. Use to create crafts neutral sealants, which hold together almost any materials well.

To use the sealant, you will need a special gun into which a tube with glue is installed. With a sharp knife cut off the tip of the spout, then wind the dispenser to control the flow. The agent is applied to a dry, cleaned surface.

Hot glue is inexpensive material to create beautiful original crafts. During use, be careful not to burn yourself, so children should use the material only under adult supervision.

Hot glue is easy to decorate tin boxes and jars, create beautiful accessories for the kitchen, create Christmas decorations.

For these purposes you will need:

• thermal gun,
• newspapers,
• jars,
• gun tubes,
• lace pieces,
• leg-split.

We wrap a jar of coffee from below with thin twine, fasten beautiful lace. You can use this container for sugar or pepper.

2. Polychloroprene adhesives based neoprene, or polychloroprene rubber (which is the same thing). These are universal adhesives for critical joints. They have good adhesion to almost all materials: metal, rubber, wood, veneer, MDF, stone, parquet, tile, ceramics, glass, and many others.

Colourpolychloroprene adhesives - tan.

By Areas of use Polychloroprene adhesives are divided into two groups:

2.1. for rigid gluing(hard adhesive seam);

2.2. for flexible bonding(flexible, elastic glue line).

2.1. Polychloroprene (neoprene) adhesives for hard glue line - these are adhesives with relatively short molecular chains, the adhesive seam of these adhesives is quite rigid and durable. Adhesives have good adhesion to metals, glass, wood, stone.

They are mainly used for fastening to hard surfaces, to metal (including painted), wood, concrete, brick, plastered surfaces) materials such as rubber, textiles, carpet, linoleum, decorative elements, skirting boards, platbands.

To improve the bonding strength, the adhesive seam can be thermally activated (heated).

Polychloroprene adhesives that you can buy on our website are "Boat", "Moment Classic universal", "88", "88+", "88 Moment extra strong", "Stealth", "Avto Niva", "317", "Neoprene", "Super Cement", "Super Monolith".

Glue "88"- one of the most famous adhesives of this group, was developed back in Soviet time Institute of Aviation Materials. "88" glue is waterproof. Water resistance is achieved due to the fact that the composition includes synthetic resin.

It is used for gluing such materials: metal, rubber, wood, veneer, stone, parquet, tile, mosaic, ceramics, glass. For fastening various kinds coatings (including flexible ones) to almost any surface. They are used for lining the interiors of cars, buses, wagons, for the manufacture of seats. Very good for gluing synthetic upholstery materials to metal.

On our website you can buy several types of "88" glue different manufacturers. In terms of properties, they are almost the same:

"88 Extra strong moment" 30g "88+" 40g and 100g,

"88" 40g and 100g, "88" (green tube) 40g.

Glue "A boat" is one of the most widely used all-purpose neoprene adhesives, designed and developed for the repair rubber boats , rubber products (car and bicycle tubes, raincoats, tents made of rubberized fabric, etc.), as well as for gluing leather, plastic, wood, veneer, polymer- synthetic materials(except for polyethylene), glass, porcelain.

When more and more boats made of PVC fabric began to appear, requests began to come in to improve the formula of the Boat glue, because from solar heating adhesive strength decreased. Then the polyurethane adhesive "PVC Boat" was developed for boats and other products made of PVC fabric.

"Moment Classic universal"manufactured by Henkel- one of the most famous and popular polychloroprene adhesives. Used for bonding various combinations: wood, metal, leather, rubber, felt, fabrics, plastics, glass, ceramics. You can buy "Moment Classic" in packages of 30 g, 50 g and 100 g.

2.2. Polychloroprene (neoprene) adhesives for flexible, elastic adhesive seam with long molecular chains designed specifically for shoes ( "Nairit", "Shoe Nairit", "Shoemaker", "Leather").

"Nairit" is a special type of neoprene rubber with long molecular chains, specially developed back in Soviet times in Armenia*. This brand of rubber was given the name "Nairit". Now "nairite" refers to all adhesives made on the basis of nairite rubber, i.e. rubber with long molecular chains. When these molecules are connected, the seam remains flexible, which is very good in the manufacture and repair of shoes. If you take glue "88" - it has a very hard glue line. And in "Nairit" the seam is soft, elastic, flexible, it does not tear under loads, vibrations, it retains gluing. For shoes - perfect option! On our website you can buy a kind of glue "Nairit" - "Shoe Nairit".

* "Nairit" plant − one of the oldest chemical enterprises in Armenia. "Nairit", as a plant of synthetic rubbers "Glavkauchuk" named after. CM. Kirov, was established in 1936. The enterprise produced the demanded national economy chemical composition− calcium carbide. Since 1940, the plant has become a monopoly producer of chloroprene rubber. Until the end of the 80s, the plant occupied 10-12% of the world synthetic rubber market.

"Shoe marathon moment" – designed for gluing shoes and shoe materials made of rubber, thermoplastic elastomer, leather, leather substitutes, fabric, felt, cork, plastic in various combinations.

"Shoemaker" – special shoe glue based on nairite rubber. Designed to connect upper parts shoes made of natural and synthetic leather with rubber and leather soles, as well as for connecting shoe elements made of artificial leather, plastic leather, textile materials. It is also used when gluing coverings, linings, gluing insoles, reinforcing elements of shoes.

"Leather" – glue of increased elasticity and heat resistance for highly absorbent materials. For the manufacture and repair of products made of natural and artificial leather, shoe uppers, fabrics, felt, synthetic materials, for attaching unshaped soles to shoe uppers.

Glue "Professional" Shoes-Leather-Rubber used for repairing shoe uppers, natural and artificial leather, rubber, fabrics, as well as repairing inflatable boats made of rubberized fabric.

Glue "Sprinter" is a universal fast-setting elastic adhesive for repairing shoes, including soles, leather, suede, nubuck, fur, polyurethane, PVC, rubber, fabrics. Can be used to bond any combination of rubber, leather, textiles, wood, metal, glass, wall tiles, ceramics and porcelain.

3. rubber adhesive is a solution of synthetic rubber in gasoline. Previously, only natural natural rubber, extracted from the sap of the South American hevea tree, was used to make this glue, but now its synthetic counterparts are used.

Rubber adhesives that you can buy on our website - "Rubber" and "Latka"- used for gluing products that do not experience heavy loads.

"Rubber" glue- this is an inexpensive adhesive for non-critical joints. It is used for gluing rubber products that do not experience heavy loads. “Rubber” glue is very popular with tanners: the details of leather jackets and other products are first baited with rubber glue before stitching, and then stitched. It is elastic and can be easily torn. Residues of glue from the material are removed simply with gasoline.

Glue "Latka" for bicycle patches, it is used to “bait” the patches, which then still need to be vulcanized.

Also rubber adhesives are applied to pasting of products from a cardboard, paper, photos.

Gluing method these three groups are almost the same. Before gluing, almost any surface to be bonded must be sanded and degreased. First you need to apply glue, wait until the solvent has evaporated so that only the rubber layer remains, and then press the surfaces to be glued and hold for some time under load.

Mode of application:

Apply an even layer of glue to the cleaned and degreased surface, dry to complete disappearance stickiness.

For responsible gluing, it is recommended to apply a second layer of glue after 10-15 minutes. after the first, also dry. The strength of the joint will increase by 1.5–2 times if the 2nd layer is heated to t ° \u003d 50–60 ° C.

Press firmly for 30 seconds. Crucial has the force, not the duration of the pressure. The product can be used after 1 hour. Final strength is achieved after 24 hours.

For polychloroprene adhesives, it is recommended to apply as much pressure as possible to the parts to be bonded. This is due to the fact that these adhesives are based on short molecules, and the stronger mechanical impact on the bonding surface, the better these molecules adhere to each other, i.e. better adhesion. There is also a recommendation - heat the seam, or thermally activate it. This is also done to improve the adhesion of the surfaces to be bonded.

In the composition of adhesiveswhich you can buy on our website, substances harmful to the body are not included, called precursors, which is confirmed by the certificates of adhesive manufacturers. At the request of wholesale buyers, we enclose a photocopy of these certificates in the product packaging.

4. Cyanoacrylate adhesives, or "super glues"

Cyanoacrylate is organic matter, the molecules of which have the ability to very quickly combine with each other (polymerize). Super glues, or cyanoacrylate glues, cure within 1-2 minutes and provide a very strong bond.

Cyanoacrylate polymerizes under the influence of moisture, which is in the air. Therefore, if you want the glue to harden faster and the air is very dry, it is recommended to breathe on the gluing site.

Also, cyanoacrylate-based adhesive polymerizes rapidly under pressure. If, for example, cyanoacrylate glue is dropped on any surface, then the drop will remain liquid for a long time.

General instructions for use cyanoacrylate adhesives:

1. The surfaces to be bonded must be dry and clean. If necessary, clean from paint, dust, degrease.

2. Apply glue to one of the surfaces to be glued.

3. Press the surfaces firmly and hold for 1-2 minutes.

Colourcyanoacrylate adhesives - transparent.

Super glues are suitable for gluing the most various materials: metals, ceramics, porcelain, glass, precious stones, rubber, rubber, most plastics, elastomers, cardboard, paper, porous materials, PVC. Used for bonding any wooden materials. Suitable for MDF, chipboard, wood, plywood. They are used in the manufacture and repair of furniture.

By consistency super glues, which you will find on our website, can be divided into 2 groups:

Ordinary, liquid cyanoacrylate adhesives

"Super Moment", "Akfix 702", "Elephant",

"505", "Cyanopan E", "Cyanopan ME",

"Alteco 110", "Retainer 505"

· Super glues - " gel", "slow", thick cyanoacrylate adhesives. They do not spread, do not absorb as quickly as conventional super glues, they are convenient to apply on vertical, uneven, porous surfaces.

"Akfix 705", "Akfix 705 with activator",

"Super Moment Gel", "Alteco Gel", "Fixator Gel"

Special precautions must be taken when working with these adhesives. precautionary measures:

1. If in the process of working with glue your fingers accidentally stuck together - do not try to break them! Carefully and slowly separate them with a round object (such as a pen). After a while, the sebum itself will reject the remnants of the glue.

2. If the glue gets into your eyes, you need to immediately rinse them large quantity water and see a doctor. If glue gets inside, make sure that the airways are clear. Cyanoacrylate polymerizes (hardens) instantly in the mouth, making it nearly impossible to swallow. Saliva will gradually separate all the solid product.

4. Keep glue out of the reach of children!

5. Epoxy adhesives

On our website you can find two-component epoxy adhesives, creating a super-strong, hard surface, which, after hardening, does not shrink, does not deform. After hardening, it can be drilled, sharpened. Adhesives are waterproof, non-flammable.

Glue metal, plastic, rubber, wood, ceramics, glass, crystals, stones and jewelry (bijouterie).

Glue epoxy two-component "Alteko 5 min" transparent for glass, ceramics, porcelain, crystal, crystals, jewelry, bijouterie.

Glue epoxy two-component "Alteko 4 min" black for metal, plastic, rubber, wood, stone, ceramics, glass.

There are other types of epoxy :

· in bottles in sets with hardener: "Khimkontakt-Epoksi" 200 g, 100 g, 70 g.

· in iron cans 900 g and 3 kg with or without PEPA hardener.

· epoxy glue universal and for steel in syringes for easy mixing,

· cold welding (all of them are made on the basis of epoxy resin)

In addition to all the above adhesives, there are also other types of adhesives available:

Adhesives in cans

· PVA glue

· Glue "Dragon" universal polymer

Glue for patches

Wallpaper glue

One of the most popular materials in construction and many other manufacturing industries is wood. Therefore, it is often necessary to glue wooden parts for the purpose of obtaining For this, an extensive range is offered various formulations, thanks to which there is no task easier than gluing a tree to a tree.

Types of glue

Of all the types of adhesive that differ in their composition and characteristics, it is necessary to choose the one suitable for solving the corresponding task in order to obtain perfect result.

• quickly and efficiently glues wood, leaving almost no traces. But when exposed to water, as well as low and high temperatures, it partially loses its properties.
• "Moment" is a universal waterproof glue for gluing wood and more. It is also effective for gluing other materials to wood. Provides instant grip.
• for wood does not lose its properties under the influence of high temperatures, does not dry out and does not crumble. Therefore, it is most often used in carpentry.
• differs in the increased adhesion at pasting of firm wood. Full adhesion is achieved 20 hours after application. Not afraid of moisture, resistant to high temperatures and prolonged loads.
• Casein glue has the same characteristics as polyurethane. The disadvantage is its ability to change the color of the glued wood.
• suitable for all types of wood, dries completely after 24 hours and leaves no residue.

Which composition to choose

When deciding how to glue a tree to a tree, it is worth considering the versatility of using the adhesive composition. Some types are suitable only for working with a certain type of wood, others are able to glue completely different types of wood.

It has great importance and what specific goals need to be achieved, for example, glue broken wooden objects or perform facade work. Important role while playing the composition of the adhesive and its quality.

household recipes

There are many recipes for how to make high-quality wood glue with your own hands. To do this, you can buy ready-made casein in powder form or get it at home. Put low-fat milk in a warm place for souring. When it is fermented, filter with gauze and rinse the casein remaining as a result of this process in water and boil to remove fat. Then lay it out on paper, dry well and mix with borax (1 part borax to 10 parts casein) until the consistency of the dough. Dilute the resulting mass with water (2 parts) and apply the resulting adhesive immediately, because it hardens after 2 hours.

General rules for gluing

There are rules for gluing wooden parts that must be observed regardless of which adhesive composition is chosen.

First you need to thoroughly clean the surface. This can be done using sandpaper or a file. After that, dry the parts and thin layer apply the adhesive with a brush and rub in gently. All surfaces intended for connection are lubricated with glue, then they are tightly pressed against each other using a press or in another way until the composition is completely hardened.

When working with any glue, precautions are required, because even the most harmless composition can sometimes cause a severe allergic reaction. Therefore, gluing wood must be carried out in rubber gloves. If the glue still gets on the skin, you need to gently wipe it off and thoroughly wash the affected area with soap. In case of contact with eyes, rinse them immediately running water.

If you carefully understand how to glue wood to wood, and strictly follow the instructions for using the adhesive composition, then the junction of the parts can be much stronger than the wood itself.

Often in everyday life or in the manufacture of furniture, we have to glue various materials together. In the carpentry and furniture business, the skills of the master in this type of work play a big role.

The quality of bonding depends primarily on the pre-treatment of the surfaces to be bonded. The surfaces to be glued are thoroughly cleaned of dirt, grease, residues of old glue or paint, the surface must be dry and clean. Materials with a mirror-smooth surface do not adhere well to each other, so clean them with a knife, sandpaper or a file.

When gluing metal, porcelain, glass stone and some other parts, you must first degrease them by washing them with warm soapy water and then rinsing. You can also degrease the surface by wiping them with a swab dipped in a solution ammonia gasoline, acetone, baking soda solution.

When gluing various materials, you need to follow a few rules: apply glue to the surface only in a thin layer, but so that there are no missed places. The glue must be free of any impurities (sawdust, dust, and so on) and of a homogeneous consistency, that is, it must not contain lumps. thick layer thick glue does not contribute to a more durable bonding. Some types of adhesives, according to the instructions, should be heated before use. We would advise you not only to heat the glue itself, but also to heat the materials to be glued. Then the bonding strength will increase.

As a rule, the parts to be glued are dried in heat not lower than 18 °C. The parts should be pressed tightly against each other with a press, oppression or vice.

When gluing wood, it is recommended to heat the surfaces to be glued. It is desirable that the humidity of the parts to be glued be the same, but, in any case, does not exceed 10-12%. Dry wood we would recommend you glue with animal and synthetic adhesives. Animal glues include bone and casein. We note right away that the preparation of bone glue for work requires quite a lot of time, but this disadvantage is more than offset by its advantages. It is beneficial to use when a large amount of work is being done. The joints glued with this glue are very strong, which distinguishes it favorably from others, even expensive ones, such as BF-2. The glued parts can withstand a load of up to 60 kg per 1 sq. cm, which is several times higher than that of other adhesives. And finally, dry wood glue tiles can be stored for an unlimited time, they practically do not deteriorate.

Wood glue should be prepared in a special glue pot. The glue cooker consists of two tin vessels, one of which (wider) is filled with water, and glue is poured into the second (smaller) and placed in the first. Glue cooker can be successfully replaced with ordinary tin cans, one of which is larger than the other. Such a device water bath) does not allow the glue to burn and can keep heat for a long time. To weld bone glue, first break the dry glue into small pieces and fill it with water. Let the glue swell for 10-12 hours, and then set to boil. For cooking liquid glue for 4 weight parts of dry glue, take 3-4 parts of water. The glue should be heated, stirring, so that the whole mass is obtained without clots and grains. Do not bring the adhesive to a boil, as this may reduce its tack and durability. Determine the readiness of the glue by dipping a stick in it.

The glue is ready if it flows slowly from the stick, in a thick, even stream. If the glue is too thick during cooking, you can dilute it hot water. When working, hot glue is used, if it has cooled slightly, it can be heated in a water bath. Don't brew right away. a large number of glue. Brew as much as you need to do the job; reheating already hardened glue worsens its properties. When preparing bone glue, you can also give it refractory properties. To do this, dissolve 100 g of glue in 200 g of water and boil it in a glue pot until a thick composition is obtained, and then add 40 g of drying oil to it and boil it again. An increase in the adhesiveness of the composition can be achieved by adding zinc or lead white to the glue at the rate of 25:2.

When preparing casein glue, take 300-400 g of water room temperature and pour 100 g of glue powder into it. Glue powder should be poured into water gradually, stirring constantly until a homogeneous creamy mass is formed. Ready mix at first it will be thick, and it is set aside for a while to liquefy. There is no need to add water to the mixture. The finished glue should flow off the stick in a continuous stream, leaving a thin, shiny film on it. Remember that casein glue is not heated, because at temperatures above 40 ° C, casein coagulates and loses its adhesive properties. You can prepare glue powder at home, provided necessary components. The glue contains 7 weight parts of dry casein powder and 1 weight part of borax (sodium boric acid).

To prepare glue from such a powder, you need 8 parts by weight of water. Pour casein cold water in a ratio of 1:1 and soak for 3 hours. Dissolve borax in hot water and pour the swollen casein with the resulting solution. Stir continuously until you get a fairly thick homogeneous mass. Parts glued with casein glue are kept under pressure for 4 hours, but the glue dries completely only after 12 hours. Big Advantage casein glue in that they can glue wood high humidity. Wood can also be glued with other adhesives such as synthetic wood glue, various resin adhesives and some other uses.

Sometimes it is required to stick plastic, leather, leatherette, decorative plywood, fabric or synthetic film on a wooden surface. Plywood can be firmly glued to wood with casein or synthetic wood glue. You can also glue plywood and tile wood glue, but it forms noticeable seam dark color. Do not apply a layer of glue directly to thin plywood as it may shrink. It is better to cover the surface of the wood with a layer of glue, and then put a plywood sheet on it and press it firmly on top with a yoke. The pressure should be about 8 kg and should lie under pressure for about 7-8 hours.

To glue plastic, use rubber-based adhesives. These can be adhesives such as 88N, Zh-3, KR-1, Elastosila-2. Before gluing, it is necessary to carefully treat the surface of wood or plastic.

Clean the wood from dust, and sand the back of the plastic until the plastic becomes slightly rough. Be especially careful with corners and edges. Then wipe the treated plastic surface with a swab dipped in gasoline to degrease it. Apply glue in a thin layer on both surfaces to be glued and connect them. Pressing the plastic firmly against the wood, run your hands from the middle to the edges to squeeze out all the air from under the plastic, and then put something heavy on the plastic so that the oppression is evenly distributed over the entire glued surface to be at least 4-5 kg ​​per 1 sq. . see Oppression leave for half an hour. Such gluings finally harden within a day.

For sticking to wooden base fabrics, leather, leather substitutes, use glues: "Oak", "Unicum", BF-6, "Polyvinyl acetate".

Also at home, with the necessary components, you can prepare a high-quality adhesive composition. For this you need 400 g wheat flour, 30 g of rosin, 15 g of aluminum alum and 100 g of water. Mix the dry ingredients, fill with water and put on low heat, or even better, use a glue cooker. In the process of preparing the glue, do not forget to stir it periodically so that lumps do not form. As soon as the glue begins to thicken it is ready. Make sure that the adhesive composition is homogeneous. This glue is used only when hot. Leathers and leatherettes (without a fabric base), degrease synthetic films with gasoline with acetone. fabrics in pretreatment before gluing is not needed. Cover both surfaces with glue, with yourself and iron with a warm iron through a wet cloth until it dries.

It is better not to glue fabrics and synthetic films with BF-6 and Polyvinyl acetate glues, since BF-6 glue can shine through the front surface and stain the fabrics yellowish. Glue "Polyvinyl acetate" collapses under the influence of water.

It is best to glue metal parts to wood using rubber adhesives, such as Zh-3, KR-1, 88-N, 88-NP, Pateks, Elastosila-2. If you need to stick to wooden surface small metal objects (hooks, shelves), we would not recommend using the first three brands of adhesives mentioned. These adhesives form the so-called "creeping seams", that is, under the action of loads metal object will slide off the wooden surface. Before gluing, file the metal surface with a file to make it rough, and then degrease with gasoline or acetone. Apply a thin layer of adhesive to both surfaces to be bonded, clamp the parts in a vise and leave for a few minutes. Finally, the glue will dry in 10-12 hours.

For gluing smooth surfaces, use the same adhesives - Elastosila-2 glue.

Apply a thin layer of glue to the surfaces previously degreased with acetone and leave it for one hour. After that, wipe the surfaces with a swab dipped in acetone, and connect them. Clamp the glued parts for 4-5 hours in a vise. Finally, the glue will harden in 10-12 hours.

Glass is most often glued together with such adhesives as "Polyvinyl acetate", "Mars", "Supercement", BF-2, "Pateks", "Unicum". These adhesives form almost colorless seams and are not destroyed by moisture. Before gluing, degrease the glass with acetone, apply a thin layer of glue to the surfaces to be glued and let it dry a little for 10 minutes. Apply the second layer and after 2-3 minutes connect the parts to be glued. Details within 20-30 minutes should be tightly pressed against each other. The glue completely hardens only after a day.

To glue glass and metal together, take Adhesive Sealant, Elastosila-2, Unicum. Degrease both surfaces, grease with glue and clamp the parts in a clamp for 30 minutes. The glue will finally harden and become waterproof after three days.

You can glue glass to a tree, as well as stick fabric or cardboard on it with PVA, PVA-A, "Polyvinyl acetate" adhesives. Degrease the glass with acetone, grease the surfaces with glue and put the parts under the press for an hour. The glue will dry in a day.

At home, glue BF-2 or "Epoxy" is used for bonding metals. Clean surfaces from dust, dirt, rust, sandpaper. Rinse treated surfaces clean water and dry well. Degrease surfaces with gasoline or acetone. Apply glue on the surface in a thin layer and leave it for an hour. Then place the blanks smeared with glue in an oven heated to 50-60 ° C and dry for 10-15 minutes. Apply a second layer of glue to the metal and, as soon as it starts to dry (stops sticking to your fingers), connect the parts to each other. It is better if you clamp the parts in a vise and dry in the oven at a temperature of 130-150 ° C for 1-2 hours. When cold drying
completely hardens only after 2-3 days.

Epoxy glue is indispensable in some cases. It consists of two components resin and hardener.

When using it, work with gloves, as the hardener is poisonous; if the hardener gets on your hands, remove it with a swab dipped in acetone, and then rinse your hands with running water. Before mixing the resin and hardener, it is advisable to heat the resin in a bowl of hot water, but not higher than 30°C. Mix warm resin with a hardener in the ratio indicated in the instructions, and use the prepared glue as you would others.

Dear friends, I again have a question for the audience, "because you know everything." It's not that I can't glue paper. :-) But progress is moving forward, the market is littered with a million varieties of glue, and the task is serious.
Imagine a postcard like this:

Paper - 300g. It has a glossy plotter print. those. the surface is quite smooth. And this postcard, ideally, will be opened and closed several times in a lifetime, i.e. they will move it, and I would like it not to fall apart from this.

In this postcard, I specially designed everything so that large planes were glued to the ride. But when somewhere you need to glue a very small "tuck" (and the gluing plane is some 5 mm, and at the same time there is some tension, and this place will be subjected to some kind of load), it falls apart even more readily.

I have children's books, so voluminous, which will soon be 30 years old. And they still have not fallen apart (not counting those places that were simply torn off by the children with their hands). What were they glued to?

For me, by far the most reliable glue is the good old PVA. If it dries up and grabs, it holds tightly. But he has two drawbacks: if you smear them with a more or less noticeable plane, he can give waves. And it also releases quite a lot of moisture when it dries. Sometimes you put something freshly glued under the press or in a frame, and a couple of days later it comes out - wet! Those. you can’t just glue it and give it away - you have to dry it. Well, that's fine. I am mostly confused by waves in PVA.

And everyone else ... There is a so-called " hot gun"with such plastic tubes that melt and glue them. It supposedly holds well. But the layer turns out to be too thick, and it also falls off.
There are all sorts of such sticks, they are often praised. But I don't trust them either. After a while, everything glued together safely falls apart.

Still, of course, it would be nice if the glue did not get dirty too much. That's what PVA is good for - it becomes transparent after drying.

Many praise rubber glue. But he first sometimes unexpectedly gives greasy spots. And secondly, over time, it also weathers and evaporates.

There is also a normal such paste, which seems to be boiled from starch. Here's one:

But he didn't convince me either.

Accordingly, the question is: what is the best glue for paper? To keep well. Even if the bonding area is small, but there is some load? And so that there is not much dirt from him (and all sorts of greasy spots). And so that the paper, all wet, does not worry. And for a long time. So that in a year or five it will also hold on.

Well, or maybe just someone knows what's in industrial production(in printing houses?) Do they stick together bulky books and bulky postcards?
