Matting Agent - Silica 99% Content, 4-6 µM Particle Size | Non-toxic, Tasteless, High-temperature Stability

Brief Introduction:
This series of Matting Agent is produced base on the precipitation method. That is silica precipitates after adding acid to the sillica gel in the salt solution. With a process of filtration, washing, drying and ultrafine crafted forms the white fluffy matte powder. Ita s tasteless, non-toxic, non-flammable, villous and only soluble in hydrofluoric acid and alkali. No change color nor decomposition after exposure at the high temperature or under sunlight.
