Polymer paint is a composition that is manufactured using non-waste technology. These mixtures are environmentally friendly, and are formed from polymer powders that are applied to the painted surface of different products. If the coating is carried out in the factory, then after processing the surface or the product with polymer paint, the base is heated and aged at a certain temperature for several minutes.
Main characteristics
Polymer paint has many advantages, it is cheaper because it does not have solvents, which in the liquid compositions play the role of carriers for film formation. The curing time 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 multilayer application with repeated drying.
In the process, such complicated operations are excluded as fine tuning the viscosity parameter to the desired value, as well as controlling this value. Powder formulations are supplied ready-made, which ensures ease of application. Having familiarized yourself with the assortment of such products, you can choose one of 5000 colors, textures and shades. After using the composition, the spray equipment is easy to clean, since it is much easier to remove the powder than multiple layers of liquid paint.
The polymer paint creates a single-layer, rather thick coating, which allows saving due to the 100% dry matter content. When applied under pressure, powder mixtures lose up to 4% in volume, which is an advantage over liquid materials, which lose up to 40%. The resulting coatings have excellent physical and mechanical properties, and the surface is characterized by chemical resistance.
The main varieties of polymer paints
If you are interested in polymer paint, then you should familiarize yourself with the assortment of these products. Such materials may be polyester, epoxy, polyurethane or epoxy-polyester. The main advantage of epoxy paints is an excellent combination of physical, mechanical and electrical insulating qualities. Such coatings are characterized by high adhesion, are characterized by chemical resistance and mechanical strength. The bases are resistant to acids and alkalis, fuel, oil, water, which allows the use of an epoxy compound for internal and external protection of trunk pipelines.
If you plan to use epoxy polymer paints, you can use them to create a layer whose thickness can reach 500 microns. At the same time, good hardness, high impact strength and elasticity will be observed over the entire surface. However, there are disadvantages of the coating, which are expressed in limited weather resistance. In open areas, chalking and a tendency to yellowing may occur, which occurs due to overheating.
Scope of use of epoxy polymer 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, coatings replace many types of complex electrical insulation. The epoxy coating can be used to cover electrical cabinets, office fittings, medical equipment and household supplies.
Scope of use of polyester polymeric paints
Such compositions are used to decorate household items, garden, medical, metal, office furniture, sports equipment, as well as electrical equipment, etc. Polyesters are in great demand due to their unique decorative qualities. Modern technology for the manufacture of powder paints has allowed to expand the color gamut of coatings and achieve different textures.
Areas of use for polyester and polyurethane polymer paints
Polyester paint for polymer coatings is used for processing travel accessories, agricultural machinery, car wheels, as well as aluminum and steel profiles for door and window openings. Polyester compositions are universal, as they can be used for indoor and outdoor use. As a result, it is possible to obtain a glossy surface, the gloss of which reaches 90%. As an alternative solution, you can choose a polyester mixture, which allows you to form a matte or semi-matt surface.
Polyurethane paints on a polymer basis are characterized by a stable gloss, are characterized by water and weather resistance. They are excellently exposed to 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 varieties of chemical equipment and containers designed to store gaseous and liquid chemicals. Polyurethane paints can be applied as a primer before using other powder paints, such as polyacrylic or epoxy.
Purpose of polymer paint for metal
Polymer paint for metal contains a solvent, special additives, polystyrene, as well as pigment. This mixture is also called liquid plastic and is a solution of ground polystyrene in solvent or toluene. Considering the polymer composition for a metal, one can cite PS-160 as an example. This mixture is used for processing pipelines, protecting the metal structures of swimming pools, for coating metal floors, as well as for painting load-bearing elements of buildings. As for pipelines, heating mains should be included here. 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 in the repair and painting of metal roofs. Before applying this composition, it is recommended to use a primer. Among the characteristics of these mixtures, one can single out a long service life, which reaches 20 years. It is impossible not to mention the possibility of obtaining a long-lasting and durable coating, excellent resistance to high humidity, temperature extremes and exposure to the sun. Among other things, these paints are thermo- and frost-resistant. After application to the surface, they dry quickly enough, forming a thin, smooth and extremely durable protective film. During operation, it exhibits qualities of resistance to chemicals and various detergent mixtures. Applying acrylic paints is very simple, they do not require the use of expensive equipment. Acrylic polymer compounds have a high adhesion to the base, they are environmentally friendly and harmless to human health.
Polyurethane polymer paint for concrete
This coloring matter acts as the most stable before the influence of negative factors. Surfaces are not afraid of petroleum products, chemicals and solvents. Due to this characteristic, polyurethane paint can be used for painting garages, hangars, industrial premises and basements. The surface after coating with this product gains the quality of protection against shock and mechanical damage. The layer can be glossy or matte, and you will spend about 400 g per square meter. Before starting work on painting, the surface is treated with a primer, and then polyurethane paint is applied in 2 layers. The second of them should be applied only after the first has completely dried, which will happen in about a day.
Conclusion
Among the polymer paints you can find universal ones, such as epoxy, which can be used for interior and exterior use. The advantage of this dye is that it is able to replace the primer, allowing you to save.
