SYLYSIA® 380
Fuji Silysia Chemical USA Ltd. · SYLYSIA®
SYLYSIA® 380 is a 9.0 µm average particle size, non-treated, amorphous silica powder used as a matting agent, anti-blocking additive, and thickening agent. It is engineered for high-efficiency gloss reduction and improved surface uniformity in coatings, plastic films, and inks. SYLYSIA® 380 provides excellent anti-blocking and flow enhancement at low loading levels due to its high porosity and consistent particle distribution. This product is particularly effective in adhesives, paper, and personal care formulations, delivering long-term viscosity stability and improved adhesion performance in both solvent-based and waterborne systems.
