With development modern technologies there was a huge variety of unique products that carry decorative effect. And thermochromic paints can be safely attributed to such goods. They are great for creating souvenirs and unique household items. They also proved to be excellent in the creation of children's dishes, as they are able to report the temperature of food. In general, the scope of use of thermochromic products is quite large, and every year it is more and more integrated into everyday life. modern people. The unique properties of the paint allow it to be used anywhere, because it does not harm a person and can perform both decorative and practical functions.

Basic information

Thermochromic paints contain special pigments that react to temperature changes. That is, when in contact with a hot or cold object, the paint completely changes its appearance. Each pigment is a microcapsule, which, in fact, provokes a change in color, affecting the entire object as a whole. The range of temperature influence is quite large. Depending on the goals pursued by a person, the paint can change at temperatures from -15 to +70 degrees.

There is a reversible and irreversible thermochromic paint, the composition plays a major role in this classification. In the case of reversible, after the temperature of the object returns to normal, its appearance will be restored. In the second type, a pattern that appears under the influence of heat or cold will remain for a long time. Usually they choose the option where, under the influence of heat or cold, the paint disappears or, on the contrary, appears.

Properties

Such paints do not harm human health, they are non-toxic, do not contain radiation or other harmful substances. Their range of applications is quite wide as they are chemically stable and can be perfectly combined with other chemical media such as printing inks, resins, plastics or rubber.

Impact range

If the reaction of the dye occurs at a temperature below 20 degrees, then basically such a dye is used as an indicator for soft drinks or other foods that should be served cold. In other words, by putting the bottle in the refrigerator, a person will be able to determine when it has cooled down enough by looking at the label, which shows the color change.

With a temperature response range of 29 to 31 degrees, paint is mainly used for things that the human body comes into contact with. For example, it is perfect for creating modern, unique t-shirts that change color when touched. Also, thermochromic paint is ideal for advertising booklets that encourage a person to touch them, and then additional information appears from the touch.

If the paint reacts to hot temperatures in excess of 43 degrees, then it is ideal for cups and other utensils intended for hot drinks and food. She can play like decorative role for a souvenir, and have a warning character.

Usage

Basically, such paint is applied to textiles or ceramics, less often - to plastic and glass things, very rarely - to paper. Recently, it has also become possible to apply thermochromic paint to cars. This allows not only to improve the appearance of the machine, but also to reduce the heating of the metal in hot weather. summer days. Besides, this perfect option for those who love dark color car, but does not want the interior to overheat in the summer.

The most popular option, where thermochromic paint is used, has become a pattern on ceramic and glass mugs. Almost every man at least once in his life was given such dishes, where, when pouring hot drinks, part of the image disappeared or appeared. Also, this development has found its application in clothing. In addition to interesting decorative and gift options, such things can warn of freezing or an increase in body temperature. Similar patterns are also applied to overalls.

Thermochromic paint has found its application in the production of goods for children. For example, there are signal signs on dishes and bathing toys that tell you what the temperature of food or water is. Many drinks that should be drunk chilled also use markings made with this paint. They can be applied both on the bottles and cans themselves, and on the labels.

Another advantage that thermochromic paint has is the price. It is quite low, taking into account the properties of this material (1500 rubles for a 25-gram jar, which is enough for a long time). Such solutions attract customers and are an excellent advertising move. Fashion magazines and advertising literature also often use paint that changes color at different temperatures. Another area of ​​application of thermochromic dyes is the creation of protective elements on medicines and cosmetics.

Light fastness

It is worth noting that thermochromic paint is extremely sensitive to ultraviolet radiation, so experts do not recommend storing it in places where there is direct sunlight. Practice shows that from sun exposure the product loses its properties in just a week. In addition, the paint is affected external factors, so for outdoor use, it is recommended to apply another layer of UV protective varnish on top of it. As a result, the product will last longer.

Usage Method

The main thing to consider when mixing paint is what effect you want to get in the end. For example, with regard to oil and water bases, then it is worth adding from 5 to 30% of the main component, but if the paint is applied under pressure, then no more than 5%. In this regard, before starting the production of a series, it is worth in any case to test the equipment and check how high-quality the effect is in the end.

Printing with thermochromic inks is extremely simple and inexpensive, while the effect of it is memorable. And if you carry out all the protective manipulations with an additional layer of coating, then the image will be durable and reliable.

Thermochromic paints are materials that tend to change color or discolor when the temperature changes. The scope of its application is very wide - art, printing, embossing, handicraft, automotive industry, the material can be applied to ceramics, plastics, textiles, glass, paper. This enamel is mainly used in decorative purposes, but as an indicator of changes in surface temperature, there are two types:

1. returnable (returning its original color after temperature drop).
2. Non-returnable (do not return the previous color after thermal exposure).

Thermochromic paint changes color with temperature

The pigments that are part of the paint, which are based on liquid crystal technology, are responsible for the color-changing properties, they are contained in the microcapsules that make up the paint. The shell of the capsules retains liquid crystals, making this material can be mixed with acrylic and other types of paints, or, in some cases, with clear varnish, printing ink, plastic, rubber, resin. Temperature changes can occur both at work and at home - with your own hands.

The paint is heat-resistant, non-toxic (meets all the requirements for the production of children's goods), has a good chemical reaction, its use in the automotive industry helps to reduce the "greenhouse effect" and allows you to feel as comfortable as possible in the car interior even in very hot weather.

The percentage of paint in the composition of the solution:

• 5-30% - in bases on a water and oil basis.
• 0.5 - 5% - in plastics.

The proportions vary depending on what result you want to achieve.

Temperature effect

Thermochromic paints, which are returnable, after the end of exposure to temperature, return the color to its original state. Each type of this material has its characteristic activation temperature. When heat-resistant enamel is heated to the activation temperature set for it, the pigment becomes colorless, and when the degrees drop, it returns to its original state.

Permissible temperature range from - 15 to + 70 degrees Celsius.

• Below + 20 degrees - for applying the substance to the dishes that will be used for soft drinks.
• + 29 ... + 31 degrees - suitable for surfaces that will change their color when exposed to body temperature (when touched). The use of this effect is widely used in advertising, on T-shirts, in magazines and on booklets.
• Above + 43 degrees - materials intended for products that will interact with hot temperature(dishes for hot drinks). In this case, the color change effect performs not only a decorative, but also a warning function.

For application on mugs, thermochromic paint with a barrier below +20 degrees Celsius is used.

The most heat exposure - 280 C, but it is better to process at lower rates, for example - 230 C, especially when using more heat-sensitive materials (plastic, textiles)

Application methods

Applying thermochromic enamel to the surface is no different from covering with ordinary paint and you can do it yourself: with a roller, spray gun, brush or sponge. When working with an airbrush, the application will be as uniform as possible, with minimum flow paints.

20 ml of acrylic enamel with pigment added is enough for about 0.3 square meters, depending on what saturation you want to achieve.

In case of application on non-absorbent surfaces, the paint should be diluted with a water-dispersion varnish or any other acrylic emulsion.

When covering the surface with material on water based wait a few minutes for the paint to dry, or shorten the waiting time by blowing hot air.

Application

• Dishes (mugs and bottles for hot and cold drinks made of glass or ceramics. Putting such a bottle in the refrigerator, it is very easy, without touching it, by color, to determine how much it has cooled and is ready for use).
• Clothes (t-shirts with drawing).
• Magazines.
• Promotional materials.
• Children's products (for example, toys intended for bathing as entertainment for a child, or dishes with which it is convenient to determine the temperature of the liquid poured into them).
• Protection for packaging (on pharmaceutical or cosmetic products, non-returnable heat-resistant substances are used in this area).

When applied different types substances, the color may change not by one, but by several, depending on the degree of heating.

Solvents

Heat resistant paints are compatible with the following solvents: water, white spirit, ethanol, xylene, butanone oxime. Incompatible given material with acetone, propyl acetate and ammonium. You can dissolve the substance with your own hands at home.

Do not use acetone thinner with thermochromic paint

Thermochromic materials should not be stored in direct sunlight as the ink may lose its color changing ability. It should be borne in mind that the shelf life of thermochromic paint does not exceed two months, after which gelation occurs.

Life time heat-resistant enamel will increase if you use top coat– UV- protective varnish.

Before launching the serial production of materials with application, it is necessary to conduct on-site tests on your own, with your own hands, since the final effect depends on many factors and can be different, so during testing you will have the opportunity to adjust the temperature, mixing proportions and shade.

The process of fluorescence became known by George Stokes in the mid-nineteenth century. Its main meaning is that some substances can absorb light particles with one wavelength (energy), and emit with a shift towards longer wavelengths (energy reduction) due to nonradiative relaxation processes. The use of this phenomenon in the paint industry is reflected in a specific type of product - fluorescent paint.

What is fluorescent paint

Fluorescent effect paint has the ability to convert ultraviolet radiation with a shift into a spectrum visible to the human eye. Thus, under the influence of UV rays, the surface with such a coating begins to glow. rich color. At daylight such paint gives a brighter and more noticeable color. At night, the paint can only glow under the influence of ultraviolet lamps.

Depending on the type of pigment, fluorescent paint is:

• Visible - in the absence of ultraviolet radiation, it has its own color.
• Invisible or colorless - does not have its own color, when exposed to ultraviolet light, it acquires a light blue, yellow, red, pink glow. A pigment can be used that only shines when exposed to a certain wavelength.

Fluorescent paint, unlike luminescent paint, is not able to autonomously glow in the dark after accumulating a charge from a light source.

Application of fluorescent paint

Fluorescent effect paint is widely used in various fields activities:

• The perfect solution for outdoor advertising. Under the influence of daylight, it stands out and attracts attention against the background of any other surrounding color. At night, with the help of illumination of ultraviolet lamps, it acquires a bright glow in the dark.
• Used for original design solutions in entertainment centers, clubs, cafes.
• For marking fences and parking lots, runways.
• For artwork, painting, children's creativity.
• For body painting (face painting, temporary tattoo).
• For inscriptions on special vehicles, rolling stock.
• In modeling and modding.
• To create paintings with a fluorescent effect on concrete walls, stones, tiles. Creation of stained-glass windows and drawings on glass and ceramics.
• For painting metal elements car bodies, disks - use aerosol paint in cans.
• In the textile industry for dyeing fabrics, creating images and photos on T-shirts.
• Stamp fluorescent ink for making invisible marks on cardboard and paper.
• The fluorescence effect is used in the manufacture banknotes for counterfeit protection. If you illuminate such a banknote with an ultraviolet lamp, you can see signs that are invisible under ordinary light.

Ultraviolet radiation

The natural and most intense source of ultraviolet waves is sunlight. When passing through the atmosphere, only UVA radiation with a wavelength of 315-400 nm reaches the earth's surface (only a tenth is absorbed atmospheric layer) and a small part (about 10%) of UVB with a length range of 280-315 nm.

The level of UV radiation can be affected by:

• The position of the Sun at a certain time of day and season.
• Surface height above sea level.
• The degree of cloudiness. Small clouds practically do not delay UV rays.
• The thickness of the ozone layer.
• Surface properties to reflect ultraviolet radiation.

In the shade, UV radiation is reduced by half or more, depending on the reflective properties of surrounding objects that are directly exposed to ultraviolet radiation. Snow is the most reflective and can reflect up to 90% of UV rays.

Luminous paints with a fluorescent effect: composition and application features

Fluorescence Properties paintwork gives a special pigment. It consists of particulate matter resins that are stained with fluorescent dyes (rhodamines and aminophthalimide derivatives). Pigments can be made for aqueous paintwork materials and solvent-borne systems, the latter being characterized by increased solvent and light resistance.

When mixing a paint material designed for certain types of surface with a compatible fluorescent pigment, a fluorescent paint is obtained. Thus, the pigment itself does not affect the scope and conditions for applying a film-forming fluorescent coating, it depends on the properties and purpose of the paintwork material. The most widespread received with a fluorescent effect.

The main disadvantage is poor resistance to direct sunshine which leads to rapid burnout. Overcome by applying additional transparent coatings with protective features. Another disadvantage is the difficulty of obtaining glossy finish due to the relatively large (up to 75 microns) size of the fluorescent pigment in the paint. It should be noted that the heat resistance of dyes is limited to 150-250°C.

Glow intensity at artificial lighting depends on the power of the UV lamps used, the number of layers applied and the color of the pigment (yellow, green, red have a higher saturation).

When preparing the surface for painting, except for traditional different types paint and varnish materials of action, manufacturers recommend covering the surface with a special primer paint white color. This enhances the fluorescent effect and reduces ink consumption.

For body art, a special mixture of fluorescent pigment with water, glycerin and lanolin is used. Before applying to the body, it is imperative to establish whether there is an allergic reaction to the coloring solution. To do this, a test smear is applied in the inner region of the elbow joint, if after half an hour there is no redness, then the paint can be applied to any part of the body. Wash off the paint with soap and water and special scrubs to completely cleanse the skin.

If fluorescent dye is used for outdoor work, then the freshly painted surface should be covered with an additional layer of varnish to increase the protective properties and resistance to direct sunlight, which increases the life of the coating. To avoid deterioration of the glow, do not use a protective varnish with a matte surface.

DIY fluorescent paint

To make your own paint with a fluorescent effect, you need:

• A clear lacquer designed for a certain type of surface.
• Powdered fluorescent pigment.
• Thinner suitable for the chosen varnish.
• Glass container.

In a glass container, one part of the pigment is proportionally mixed to four parts of the varnish. For a more uniform distribution of the pigment and obtaining a uniform consistency, a solvent is added in small quantities. By changing the proportions, you can change the brightness and saturation of the glow, get more "poisonous" or "soft" colors. The resulting paint is applied to the surface in 3-4 layers.

The relative ease of manufacture and the growing popularity of fluorescent paint materials leads to wide choice products from different manufacturers. Positive reviews according to the price-quality parameter, Decola art sets of fluorescent paints from the Nevskaya Palitra plant are received. For decorative and design work, it is profitable to buy a fluorescent acrylic enamel in spray cans of the Kudo trademark.

Market construction technologies does not stand still and periodically surprises consumers with its new products. One of them is an ultraviolet paint, invisible in daylight, which is widely used today by decorators and designers.

Its name involuntarily evokes fantastic associations, although in fact it is quite ordinary material for interior decoration.

Kinds

The range of such products can be conditionally divided into two groups:

• luminescent;
• fluorescent.

Each has its own special properties, which determine the specifics of their application, as well as a wide range of colors. These materials are based on insoluble and opaque alkyd or water-based pigments. During the day on light surfaces, they are almost impossible to notice, at the same time on dark coatings they look like whitish traces.

We will linger a little on pigments, since when painting any surface it would be good to know more information about them. For example, each coloring agent has such a characteristic as hiding power, i.e. how much material is required to paint a conventional amount per unit area.

If you take an ultramarine pigment, it will take about 50 g / 1 m 2. By the way, not many people know from which mineral ultramarine paint is obtained: natural from lapis lazuli, but artificially- from a mixture of kaolin, Glauber's salt, soda, sulfur and coal.

Azure can be a standalone tint or used to enhance the color. Now you know what ultramarine paint is made of - what mineral it was first obtained from, and you can always give the correct answer.

fluorescent

1. Invisible paint glowing in the ultraviolet, the shades are brightly acidic.
2. Paint colors:

• lemon;
• yellow;
• blue;
• blue;
• red;
• brown;
• purple;
• mustard;
• purple;

as well as other colors.

1. invisible black acrylic paint does not glow in ultraviolet rays, but makes it possible to create 3D shadows in the drawings.

1. Material used for design:

• residential premises;
• clubs;
• restaurants;
• and decoration of textiles and sports equipment;
• signal signs.

fluorescent

This type of invisible paint can accumulate light energy, which then gradually gives off, glowing in the dark.

The duration and intensity of the glow depends on:

• pigments and their qualities;
• intensity and time of light exposure of the material;
• base layer colors;
• degree of illumination.

In normal light, it has a pale greenish tint, but in the dark it begins to glow brightly in the corresponding color.

Luminescent paints can be:

• yellow;
• blue;
• green;
• purple;
• orange;
• red.

Invisible luminescent paints can only glow with these colors:

• blue-green;
• green-yellow;
• blue.

The material has found its application in interior decoration, it is applied by hand on wallpaper, as well as others. decorative coatings, they are decorated with decorative elements, including ceiling lamps, candlesticks and vases.

Places of application

For interior

Acrylic-based paint designed specifically for the protection and decoration of indoor wallpapers. Such materials dry very quickly, have chemical and mechanical resistance, as well as high elasticity. Each comes with instructions for use.

Special additives in the composition prevent the appearance of mold and fungi on the painted surface.

Used for ceilings and walls made of dense and porous materials:

• bricks;
• cement-lime plasters;
• concrete;
• wallpaper.

For metal

They form a glossy transparent coating.

Possess:

• weather resistance;
• increased strength;
• oil resistance;
• detergents;
• some organic solvents.

Have high level drying, used for and outdoors. They are used in airbrushing, auto tuning, for painting car rims, in decor and design of exteriors and interiors.

Tip: when using fire-retardant paints for metal Polistil.

Paint bases

AT this moment invisible fluorescent and fluorescent paints can be alkyd and water based.

Consider below their characteristics:

1. Water-based materials are non-toxic, their price is quite affordable, they do not have a specific smell, therefore they are much more often used for interior decoration of residential premises and entertainment facilities. In addition, they can be successfully used for the design of facades and other finishing works outside buildings.
   Paints are resistant to external influences and are not washed away by rain and snow. They should be applied to previously degreased wood, glass, metal, fabric and stone surfaces.
2. The alkyd base can withstand various influences to a greater extent, in addition, it is not washed off the surfaces. detergents. Due to toxic fumes during drying, such paints should be used for external design.

For example, use compositions when decorating the facades of buildings that will acquire an original appearance with appropriate lighting. Often they are used when decorating entrances to restaurants, sports clubs, discos, bars and other similar establishments.

Conclusion

If you want to give the interior of the room or the house the outside original look, use special luminous paints for this. They are of two types - fluorescent and luminescent, differing from each other in special characteristics. The video in this article will help you find Additional information on this topic.
