Soft composite silicon powderIt is a non-metallic material that is odorless, non-toxic and non-polluting. Most silicon powders on the market are obtained through low-cost physical methods. At present, silica powder is widely used in rubber, plastics, ceramics, coatings and other industries.

According to the interaction between silica powder and structurally similar titanium dioxide, Wang Pengzhu and others applied silica powder-titanium dioxide composite powder to latex paint, and its pencil hardness was significantly higher than that of all-titanium dioxide latex paint. Liu Zongwang and others added silicon powder to the unsaturated polyester insulating paint to improve the water absorption, electrical strength and volume resistivity of the insulating paint. The mechanical properties and electrochemical properties of organically modified silica powder coatings were studied.

At present, there are few research reports on the wear resistance, high hardness and durability of epoxy/polyester powder coatings. By adding silicon powder, the mechanical properties such as hardness and impact resistance of epoxy/polyester powder coatings are improved. It can be used for surface coating of automobiles, household appliances, hardware, building materials and pipelines.
