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…
