1. The glass powder has good transparency, high hardness and uniform particle size distribution. 2. The glass powder has good dispersibility and good compatibility with other components in the resin and paint system. 3. The glass powder has been surface treated for many times and filled in the paint system. The paint film does not have blue light and has good recoatability. 4. Used in professional scratch-resistant topcoats, it can increase the hardness and toughness of the topcoat, and improve the scratch resistance of the paint film. It has a matting effect and can improve the weather resistance of the paint film. 5. Compared with talcum powder, glass powder is easier to precipitate after the paint is diluted, so the anti-settling measures should be strengthened appropriately.
