Matting Agent
CAS Number: 112926-00-8
Synthetic amorphous silica matting agent designed to reduce gloss in coatings, paints, and varnishes without impairing transparency or film properties. It provides efficient matting performance at low dosages and is compatible with both solvent-borne and waterborne systems. Particle size is precisely engineered to deliver uniform scratch resistance alongside excellent matting effect.
