Progress does not stand still, and each industry gradually gets its own development. The sphere of construction and renovation is always in step with the times, and therefore is constantly supplemented with new technologies and products. Powder paint is a new type of similar materials, which has found its place in a number of similar materials and is actively used for painting various products and surfaces.
Features of the
Powder paint was invented a long time ago, but right now it has gained the greatest popularity. Its peculiarity is that it is produced in the form of a powder and remains in this state even when applied to the surface. These characteristics allow it to obtain a number of benefits related to the environmental friendliness of the product. Unlike ordinary paint, there are no organic solvents here, so it is completely safe for humans.
The process of applying such material is carried out using special equipment, which allows you to work economically, without wasting more than necessary and without polluting the environment with elements that do not fall on the painted surface.
If we consider the composition of the paint, then only two components can be distinguished in it, solid particles and air. A distinctive feature of this powder is its insolubility in water, lack of smell and a certain color. By adding certain impurities, the desired shade can be obtained.
Considering the composition in more detail, you can find a hardener, a film-forming resin, a filler, a pigment and a target additive in it. The advantages of such a paint are undeniable, and most importantly, when working with it there is no need to use a solvent, because the structure does not change its properties under any circumstances. The technical characteristics of this material make it possible to use it for painting a wide variety of surfaces, among which are:
- metal surfaces;
- household appliances (microwave ovens, refrigerators and more);
- sports equipment, equipment for athletes;
- glass and ceramic products;
- elements of machines.
The surfaces to be painted with powder paint can be very diverse. This type of staining is of particular importance in the case of staining pipes inside, which are under high pressure. This material can withstand high temperatures, so not every type of paint can be used for interior decoration.
Such an abundance of options for materials that can be painted with powder paint offers great opportunities. The properties possessed by the new coating allow not to be afraid for the health of people, because the harmfulness that some components of ordinary paints and varnishes possess are completely absent in this composition.
Types and application
Unlike conventional paints, powder paints have a completely different principle of surface painting. Having electrical insulating properties, its particles are charged by an electric field, which differs from the surface that will be painted. Thus, getting on it, these tiny grains of sand simply stick to the surface. It is not possible to paint the surface well at a time, therefore this procedure is repeated twice. As soon as the surface has been covered with a layer of paint, it is imperative that high temperatures are applied to bake it.
Depending on the surface to be painted on, be it the outside or inside, and some other properties allow classify this material into two main groups:
If we talk about the first option, then it is often used for painting metal and chrome products. After the paint has been applied to the surface, a special protective film is formed due to the heating of the material, and then its cooling. It is heat-resistant, if the mode of operation with it is observed correctly, otherwise the film will quickly dissolve.
Knowing the conditions in which the painted surface will be used, the following types of paint can be distinguished:
- Vinylite is a base, but you can mix it with other additives and use it for decorative purposes. The main element of the colorant is suitable for indoor use only. The layer thickness is small, but even so, the level of protection is very serious.
- Polyvinyl chloride finds its application in the work on the external and internal surfaces of objects. It is applied both outdoors and inside. PVC-based paints have a composition that is resistant to chemicals and weather conditions.
- Polyethylene compound possesses high indicators both in physical and mechanical properties, which is why they are used for painting the pipeline.
- Paint with polyamide They are distinguished by good external performance and are used for decorative finishing of the premises outside and for all internal work.
If we talk about the second version of paints, then they form a film after drying. The composition of such a coating does not undergo any changes in the type of dissolution or melting, which means that the finished product will have characteristics that are resistant to various kinds of defects. Polyester and epoxy resins, polyurethane elements and acrylates are the basis of the composition.
The polymer-epoxy structure makes it possible to successfully use this type of paints in mechanical engineering. The antistatic function is inherent in polymer powder paints. In order to give the car an interesting look, you can add a luminescent pigment, this will make a fluorescent car paint.
Epoxy substances in the composition make it possible to achieve high mechanical strength of the painted surface. The only factor that can contribute to the appearance of defects is ultraviolet radiation. Only mirrored chrome can resist such factors. Polyester paint is precisely aimed at solving the problems of exposure to the sun, it does not react to its radiation. This coating can be used to decorate any external surfaces that will retain their color for a long time.
Epoxy-polyester paint contains polyester and epoxy blowing agents, which react with each other during the curing process. These paints are almost non-yellowing and can withstand high temperatures.
The acrylate base is resistant to alkalis. The pigment, which is responsible for the color, can retain its properties for a long time. The dyes that are added to powder paint can be taken in a variety of ways, which is their uniqueness.
Of the difficulties, one can only note the work with substances that are in different cans, they cannot be mixed together. The low temperature environment is unacceptable for working with metal objects when they are painted.
Colors and textures
The color variety of powder paints is huge. By using an additional dye, you can give the surface a wide variety of shades. In some cases, you can use several colors at once. There is no specific catalog in this case, each manufacturer creates its own colors.
It is customary to subdivide colors according to the RAL scale, which is considered the standard in paintwork. There are two varieties of colors:
In the classic version, seven primary colors are distinguished, from which a huge number of shades originate. Each of them is produced in two versions:
In order to make it easier to choose the desired color or shade, a special four-digit number has been developed for each color, for example:
- For the yellow series, it is 1000, 1005 and ends in 1034;
- For the purple series - 4001, 4005 and up to 4010.
As for the design scale, there are much more colors here, namely 1688. It has a classic basis, but there is a division according to the saturation and brightness of the shades. In addition, the latest fashion trends give rise to original color solutions. Antique color is considered popular, which gives metal products an antique look. Painted surfaces come in a variety of shades, including bronze, copper and silver. The glossy surface is obtained under the influence metallic effect.
You can paint the product under shagreen. Its distinctive feature is the enlargement of the texture - it resembles an orange peel. With this option, you can hide small surface irregularities. The paint helps to enhance the wear resistance of the material to which it is applied.
Another painting option is moire, which is characterized by the presence of a fine-grained pattern. Externally, the surface resembles sandpaper, pleasant to the touch. The surface strength is enhanced, as is the scratch resistance. Crocodile dyeing helps to add volume to the surface. It can be used indoors and outdoors and is UV resistant.
Another original option is painting with a hammer effect for those surfaces from which they want to get the look of old iron. The finished product looks like a chased surface, on which they worked with a hammer. This paint is resistant to atmospheric precipitation, temperature changes, vibrations, and corrosion.
Metal parts can be painted with chrome paint, which looks especially impressive on cars. Powder paint for gold can make any surface unique and give it an expensive look. The color palette of such paints has many options, but black and white still remain trendy and do not go out of fashion.
If it is necessary to obtain the desired effect from the use of powder paint, it is important not only to observe the application technology, but also to purchase good and high-quality products. One of the market leaders is the company Pulver Is a Turkish powder paint manufacturer that exports products all over the world. All products have certificates and high quality indicators. The same good reviews can be heard about the company's products. Savipol, which also pays special attention to the quality of its goods.
Of the German manufacturers, Pulverit stands out, which produces quality products. With powder paint on hand, you can safely paint aluminum and chrome parts for which silver was previously used.
Every serious company that distributes its products all over the world conducts serious tests of paints before putting them on stream and distributing them in different cities and countries. That is why, when reading reviews about any global brand, you can see mostly positive reviews, and any problems that arise during the painting process are more often associated with the incompetence of those who perform the work.
Despite the abundance of foreign brands, you can always find good offers from domestic manufacturers.In this case, it is important to take a closer look at the choice, read the main characteristics of paint from proven brands and compare them with ours.
The difference in the composition is minimal, or even none at all, and the price of Russian products is often an order of magnitude lower, which makes such a purchase more desirable
In order to make the right choice of powder paint for metal surfaces, you need to focus on indicators such as:
- Manufacturer. It is best to choose well-known brands that have established themselves in the market. Often they have both expensive and more affordable paints in their assortment, so people of different social strata can afford them.
- Selection of colors. Having a clear idea of how the finished coating should look, you can choose the exact color and shade by choosing it from the catalog, which contains a huge number of options.
- The choice of texture for outdoor painting. It is worth determining the type of surface - smooth or rough. By choosing the option with decorative irregularities, you can hide small surface defects, while maintaining all the properties of the material.
- Strength indicators and wear resistance depend on those additives that are in the paints.
- Sustainability indicators to thermal and chemical effects. The surface covered with a polymerized layer is not subject to such influences, but at certain values it is possible to enhance the properties of the paint by adding the necessary additives to the composition.
- Equipment compliance. It is important that the paint matches the equipment with which it is applied.
- Storage. When choosing powder paint, it is important to pay attention to its shelf life and conditions.
- Packing size… Each surface needs a certain amount of material, so in order not to buy too much, it is better to choose the appropriate packaging option.
The selection of powder can be done for non-metallic products, but it is important to know which one will be painted. For MDF, this is one type, but for aluminum, a different option is required.
All surfaces can be painted only with the use of special equipment, which will allow you to get a flat surface with a uniformly applied layer of paint. It will protect the surface and will serve for a long time without loss of properties and color.
