High wear resistance additives of coatings

High wear resistance additives of coatings including Water-Borne and oil coatings: silicon nitride, silicon carbide.

Silicon carbide, silicon nitride nano powder, produced by Plasma Arc Vapor Synthesis technology & reactor patented by our company- Hefei Kaier Nano-meter Technology and Development Limited Company, are hard, solid substance. They have high hardness, good shock and heat-resistant characteristics. They possess small APS, large specific surface area, high surface activity, lower sintering temperature, large high temperature strength, high mechanical strength, good chemical stability and corrosion resistance, anti-oxidation and self lubricate, high dielectric constant and resistivity. The violet reflectance is larger than 90%. They are the best additives of coatings, featuring the resulted coating films good properties such as wear aging, anti violet and chemical resistance due to the nanosize ultrafine particles and the interparticle and intraparticle crosslingkings. They can form the dispersive phase in composites. General properties such as improve electric conductivity, absorb wave of composites of nano powders with plastics such as nylon and PET are greatly improved.
