This product improves the purity of silica, adopts the gel method, optimizes in the production equipment and production process, makes the product have better particle size distribution, effectively improves the extinction efficiency, and the transparency of the product is also greatly improved. improve. The refractive index of the matting powder is improved, the refractive index of the powder and the resin are closer, and it is very easy to disperse under extremely unfavorable conditions, which is more advantageous for adjusting the matness by using a matting agent. The special treatment process is adopted to make the product and various water-based resins have good compatibility, so as to achieve good anti-settling effect.
Application areas: waterborne wood lacquer; waterborne industrial lacquer.
