SS-901 Silica 7631-86-9 Extinction Agent

SKYSIL SS-901 SIO2 POWDER FOR WATER BASED COATING SS-901 precipitated silica matting agent is a functional additive developed specifically for high-performance water-based coatings. Through precisely controlled chemical interface characteristics and multi-level pore structure, it breaks through the technical bottleneck of traditional matting agents in environmentally friendly coatings. Its surface is modified by a special silane coupling agent to form a dynamic charge balance layer, which significantly improves the interfacial compatibility with water-based acrylic acid, polyurethane and other resins. Even at low addition levels (1.5-4%), the 60° gloss can still be precisely controlled within the range of 2-8GU, and the matting efficiency is increased by more than 25% compared with conventional products. The core advantage of this product comes from its unique "core-shell" chemical structure design. The core is high-purity amorphous silica (SiO₂≥99.8%), and the surface is cov…
