Paint Matting Agent has the characteristics of large pore volume and large specific surface, insoluble in water, solvent and acid (except hydrofluoric acid). High temperature resistant, non-flammable, tasteless, odorless, with good electrical insulation, is therefore used as a matting agent in high-grade coatings, with unique properties, can achieve high extinction of the surface, and has excellent chemical resistance, excellent transparency and good scratch resistance and metal scratch resistance. In addition, silica gel matting agent disperses more easily and produces less dust.
