SYLYSIA® 450
Fuji Silysia Chemical USA Ltd. · SYLYSIA®
SYLYSIA® 450 is an 8.0 µm average particle size, non-treated, amorphous silica powder used as a matting agent, anti-blocking additive, and viscosity stabilizer. It is part of the SYLYSIA 400 series, known for high density, high porosity, and low bulk density, enabling uniform gloss control, anti-blocking performance, and enhanced viscosity management. SYLYSIA® 450 is particularly effective in coatings, plastic films, adhesives, paper, and personal care applications, offering excellent dispersion, adhesion durability, and moisture resistance across both solvent and water-based systems.
