Silicon Dioxide CAS No. 7631-86-9 as Paint Matting Agent Used For Wood Coating Application
Description
It is a synthetic amorphous silica appearing as white powder. It is a micronized precipitated silica matting agent for both solvent-based and water-based system. Silica Matting Agent reduce the gloss of a variety of products including coatings, paints, inks, lacquers, varnishes, while providing lower viscosity and better flow capability. Optimal matting efficiency is achieved by using silica with high pore volume and by fine control of the particle size and particle size distribution. It provides a superior matting and flatting, excellent coating appearance and transparency, cost efficient, effective anti-settling agent and easy dispersion, smooth, abrasion resistant films of high surface quality. Matting Agent specialized used for the matte wood coating. It provided high matting efficiency, excellent coating appearance and high transparency. As well as low oil absorption, easy dispersion and smoothly touch with minimal impact of viscosity.
