Tokuyama REOLOSIL CP-102 is a hydrophilic fumed silica imported from Japan. It features high reinforcement efficiency and excellent rheology control, with easy dispersion and low impurities, designed for coatings, silicone rubber, adhesives and other fields
Ultra-low specific surface area – uniform particle size, suitable for low-viscosity formulations without affecting fluidity
Efficient rheology control – precisely adjust liquid thixotropy, prevent sagging and sedimentation, improve construction convenience
Excellent reinforcement – enhance mechanical strength of silicone rubber and sealants, improve durability and adhesion
Easy dispersion and processing – fluffy white powder, no agglomeration after addition, reduce processing difficulty
Multi-scenario adaptation – anti-caking and flow aid functions, suitable for polishing and other special fields
Coating systems – water-based/UV coatings, leather finishing, thickening and anti-sagging, improve stability and transparency
Polishing and grinding – used as abrasive particles for polishes and abrasives, enhance grinding effect and surface finish
Silicone rubber products – reinforcement for HCR-RTV-2K silicone rubber, improve toughness and service life
Sealants/adhesives – thickening and thixotropy, prevent filler sedimentation, enhance bonding strength
Powder products – anti-caking and flow aid, improve storage and processing performance
