Powder paints contain pigments and distributed additives that are in forms of fine powders and is sprayed over the surface by an electrostatic spray. The outstanding features of these paints is that they dry quickly. The ultimate result is clean and smooth substrate, which is painted well and has a durable and suitable surface. Powder colors after firing in furnace will likely create smoke which causes dissatisfaction. To solve this problem, the present product has benefited using of silica particles. This Particles will cause increase of heat resistance, chemical and physical stability.
Using of powder Paint as an alternative for liquid paint has created a great evolution in the color quality. Liquid paints create environmental pollution because of possessing evaporative chemical solvents during drying, and they are harmful for human health. The powder paint entered to the market for the first time in 1962. Keeping of 100% solid state, in addition of environmental pollution prevention, has offered incomparable quality against liquid paints to the industry. Powder paints are now accounted for 15% of the market and compete with traditional colors liquid. Due to environmental laws on pollution and waste removal, replacement of liquid paints with powder paints become more important every day.Silica can be used as a flame prolonger in polymeric composites. The result of increasing thermal stability is reducing smoke after paint curing.
