Tokuyama REOLOSIL QS-10 is a hydrophilic fumed silica imported from Japan. It features low specific surface area and low viscosity, with efficient rheology control and reinforcement, suitable for coatings, sealants, silicone rubber and other fields.
Low specific surface area - uniform particle size, suitable for low-viscosity formulations without affecting fluidity
Precise rheology control - adjust liquid thixotropy, prevent sagging and sedimentation, improve construction convenience
Efficient reinforcement - enhance mechanical properties of silicone rubber and sealants, improve adhesion and durability
Easy dispersion and processing - fluffy white powder, no agglomeration after addition, reduce processing difficulty
High purity and low impurities - SiO₂>99.9%, extremely low impurities, ensure end-product quality
Coating systems - water-based/UV coatings, leather finishing, anti-sagging and anti-settling, improve stability
Sealants/adhesives - thickening and thixotropy, enhance bonding strength, prevent filler sedimentation
Silicone rubber products - reinforcement for HCR-RTV-2K silicone rubber, improve toughness and service life
Powder products - anti-caking and flow aid, improve storage and processing performance
Polishing and grinding - used as raw material for abrasives and polishes, enhance grinding effect
