High Purity Crystalline Quartz Filler, High Hardness Silica Glass Powder

Brief Introduction:

VGS-507 high purity crystalline quartz filler has characteristic of uniform particle size distribution, high transparency, good hardness, high purity and heavy metal free. The product offers low thermal expansion coefficient, good chemical stability and excellent optical performance. The high purity crystalline quartz filler is the best filling powder for matt paint and wood lacquer. When used in the scratch resistance coatings, the powder’s effects are equal to the international brand in most aspects such as scratch resistance, dispersion, recoatability and anti-settling etc.
