Product Description

Precipitated Silica White Carbon Black CAS NO. 10279-57-9

1.Description
his product improves the purity of silica, adopts the gel process, and optimizes the production equipment and production process, so that the product has a better particle size distribution, effectively improves the matting efficiency, and the transparency of the product is also greatly improved. improve. The refractive index of the matting powder is improved, making the refractive index of the powder and the resin closer, and it is also very easy to disperse under extremely unfavorable conditions, which is more conducive to the use of the matting agent to adjust the dullness. Special processing technology is adopted to make this product have good compatibility with various water-based resins, so as to achieve a good anti-settling effect.
A. Reinforcing: Improve the tensile strength, tear strength, toughness and impact resistance of the product;
B.Thickening, improving the product consistency of liquid system, rheological control, thickening without thinning;
C.Thixotropy, one touch change, improve the rheological and thixotropy of liquid systems;
D.Anti caking, promote and maintain the fluidity and anti caking performance of powder particles;
E.Anti sagging: prevent the liquid from flowing and sagging, and improve the flatness of the construction surface;
F.Anti sedimentation improves the adhesion of various systems, effectively prevents layered sedimentation, and is an ideal suspending agent;
G.Thermal insulation: thermal conductivity and excellent thermal insulation effect;
