Polymer paint: varieties and purpose

Polymer paint is a composition that is made by non-waste technology. These blends are environmentally friendly, and are formed from polymer powders, which are applied to the painted surfaces of different products. If the coating is carried out in the factory, then after surface treatment or the product with polymer paint, the substrate is heated and held at a certain temperature for several minutes.

Main characteristics

Polymer paint has many advantages, it costs less, since it does not have solvents, which in liquid formulations play the role of carriers for film formation. The time of solidification of such compositions is reduced, since film formation occurs at high speed. The coating can be carried out in one layer, which distinguishes this composition from conventional paints, which require the necessity of multi-layer application with repeated drying.

In the course of work, such complex operations as the fine-tuning to the desired value of the viscosity parameter and also the control of this value are excluded. Powder compositions are supplied ready-made, which ensures their ease of application. After acquainting yourself with the assortment of such products, you can choose one of 5000 colors, textures and shades. After using the composition, the spray equipment can be easily cleaned, since it is much easier to remove the powder than multiple layers of liquid paint.

Polymer paint creates a single-layer, rather thick coating, which allows you to save due to a 100% dry matter content. When applied under pressure, powder mixtures lose up to 4% in volume, this is an advantage over liquid materials, which lose up to 40%. The obtained coatings have excellent physical and mechanical properties, and the surface is characterized by chemical stability.

Basic varieties of polymer paints

If you are interested in polymer paint, then you should familiarize yourself with the assortment of this product. Such materials can be polyester, epoxy, polyurethane or epoxy-polyester. As the main advantage of epoxy paints is an excellent combination of physical-mechanical and electrical insulating qualities. Such coatings are highly adhesive, characterized by chemical stability and mechanical strength. The bases are resistant to acids and alkalis, fuel, oil, water, which allows the use of epoxy compound for internal and external protection of main pipelines.

If you plan to use epoxy resin paints, you can create a layer with a thickness of up to 500 μm. At the same time, good hardness, high impact strength and elasticity will be observed throughout the surface. However, there are also disadvantages of the coating, which are expressed in a limited weathering resistance. In open areas, there may be chalking and a tendency to yellowing, which is due to overheating.

Area of use of epoxy resin paints

Epoxy polymer powder paint is used to obtain hard coatings that are resistant to chemicals and solvents. Consumers of such powders are the fields of radio engineering and electrical engineering, in these areas the coatings are replaced by many kinds of complex electrical insulation. Covering with an epoxy compound can be electrical cabinets, office fittings, medical equipment and household accessories.

Area of use of polyester polymer paints

Similar compounds are used for finishing household items, garden, medical, metal, office furniture, sports equipment, as well as electrical equipment, etc. Polyethers are in great demand thanks to unique decorative qualities. Modern technology for the production of powder paints allowed to expand the color range of coatings and achieve different texture.

Areas of use of polyester and polyurethane polymer paints

Polyester paint for polymer coatings is used for the processing of travel accessories, agricultural machines, automobile wheels, as well as aluminum and steel profiles for door and window openings. Polyester compounds are universal, as they can be used for indoor and outdoor use. As a result, it is possible to obtain a glossy surface, the brightness of which reaches 90%. Alternatively, a polyester blend can be selected that allows the formation of a matt or semi-matt surface.

Polyurethane paints on a polymer base are distinguished by a steady gloss, characterized by water and weather resistance. They are well under the influence of mineral oils, fuels and solvents. Polyurethane paints are used to protect products that are subject to abrasion and friction. Their application can be carried out on some types of chemical equipment and tanks, designed to store gaseous and liquid chemicals. It is possible to apply polyurethane paints as a primer before using other powder paints, for example polyacrylic or epoxy paints.

Purpose of polymer paint for metal

Polymer paint for metal has a solvent, special additives, polystyrene, as well as pigment. This mixture is also called liquid plastic and is a solution of crushed polystyrene in solvent or toluene. Considering the polymer composition for a metal, one can cite as an example PS-160. This mixture is used for the treatment of pipelines, the protection of metal structures of pools, for coating metal floors, as well as for painting the load-bearing elements of buildings. As for pipelines, here it is necessary to include heating mains. Metal floors can be covered on ships, inside production and storage facilities. Such a polymer floor paint can protect surfaces that are constantly in contact with water.

Purpose and properties of acrylic polymer compositions

Acrylic polymer paints can be used for interior and exterior work in the field of facades, as well as for repair and painting of metal roofing. Before applying this composition, it is recommended to apply a primer. Among the characteristics of these mixtures can be distinguished long-term exploitation, which reaches 20 years. It is impossible not to mention the possibility of obtaining a durable and durable coating, excellent resistance to high humidity, temperature changes and exposure to the sun. In addition, these paints are thermo- and frost-resistant. After application to the surface, they dry quickly enough to form a thin, smooth and extremely strong protective film. In the process of operation, it exhibits qualities of resistance to the effects of chemicals and various detergent mixtures. Applying acrylic paints is very simple, they do not require the use of expensive equipment. Acrylic polymer compositions have a high adhesivity to the substrate, they are environmentally friendly and harmless to human health.

Polyurethane polymer paint for concrete

This colorant acts as the most stable before the influence of negative factors. Surfaces are not terrible oil products, chemical compounds and solvents. Due to this characteristic, polyurethane paint can be used for painting garages, hangars, industrial premises and cellars. The surface after coating with this product acquires the quality of protection from shocks and mechanical damages. The layer can be glossy or matte, and one square meter you will spend about 400 g. Before starting the painting work, the surface is treated with a primer, and after polyurethane paint is applied in 2 layers. The second of them should be applied only after the first one dries completely, which will happen about a day later.

Conclusion

Among the polymer paints you can find universal, which is epoxy, which can be used for indoor and outdoor works. Plus, this dye is that it is able to replace the primer, allowing you to save.
