Silica Matting Agent as White Powder CAS No.: 7631-86-9 Used For
Silica Matting Agent specialized used for the PU/PVC matte finish
leather coating. It is a micronized precipitated silica matting
agent for both solvent-based and water-based system. It provides a
medium-high viscosity with a pleasant matte finish. They resist
dripping and offer excellent adhesion and high flexibility with
wet-dry abrasion resistance.
1, Stable Chemical Property: As the matting agent is with high
purity and low impurity, its chemical property is very stable.
2, Excellent Dispersion: The matting agent can easily disperse in
both solvent and aqueous solution, the average high-speed pulsator
with 10-20 M/S of the line speed, after 10 minutes can be ok.
3, High Matting Efficiency: It can reduce the gloss for the surface
of leather, provide the better matte finish.
