Sericite Powder, 6μm

Catalog NumberACFR000031

CategoryFunctional Inorganic Powder

Description	Sericite Powder is a layered structural silicate, whose structure consists of a composite silicate layer sandwiched between two layers of silicon-oxygen tetrahedrons and one layer of aluminum-oxygen octahedrons. It features naturally small particle size and easy processing into ultra-fine powder. In addition, its chemical composition, structure and configuration are similar to kaolin, and it also has certain characteristics of clay minerals, such as good dispersibility and suspension in aqueous media and organic solvents, white color, fine particles and viscosity.
Application	1. When applied in coatings, it can improve the impermeability and scratch resistance of the coating, as well as provide good weather resistance and corrosion resistance. 2. When used in rubber and plastic products, it can reduce the shrinkage rate and warpage rate of products, enhance their mechanical properties, heat resistance, insulation and chemical stability, and improve the surface gloss and weather resistance of products.
