High-quality silica (SiO2) flatting and matting agent ideal for furniture, wood, and industrial paints, enhancing transparency, heat dispersion, and suspension.
Coating Grade Silica (SiO2) flatting and matting agent is an essential additive for creating smooth, non-reflective finishes in various coatings and paints. It effectively reduces gloss and enhances surface textures, providing a consistent matte appearance. Ideal for industrial applications, it offers excellent performance and easy integration into formulations.
Appreance:Powder
Package:10kg / Paper bag
Advantage of Silica use for Matting Agent:
1.Good Transparency
2.Good Disperse Heat
