High Purity Crystalline Quartz
Filler,High Hardness Silica
Glass Powder,
Brief
Introduction:
VGS***7 highpuritycrystallinequartzfiller 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 silica 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.
