The material used for plating is SiO2, that is, silicon dioxide, and also called quartz. The main component of the company's plated crystal is polysiloxane, which is a polymer of silica and its nano-sized polymer. The utility model forms an isolation layer on the surface of the paint lacquer. The insulation layer has a certain hardness and has the functions of resisting ultraviolet rays, oil resistance, acid and alkali resistance, hydrophobicity and oleophobicity, thereby protecting the paint surface. http://www.kisho-coating.com
