Low viscosity control – adjust liquid thixotropy without excessive thickening, improve construction fluency
High-efficiency reinforcement – enhance mechanical properties of HCR-RTV-2K silicone rubber
Easy dispersion – fluffy powder, convenient to add, reduce processing energy consumption
High purity and low impurities – SiO₂>99.9%, no harmful impurities, ensure product quality
Multi-functional adaptation – anti-sagging, anti-settling, anti-caking and carrier functions
Coating systems – water-based/UV coatings, leather finishing, anti-sagging and anti-settling
Silicone rubber products – reinforcement for HCR and RTV-2K silicone rubber
Adhesives/sealants – thickening and thixotropy, prevent filler sedimentation
Powder products – anti-caking and flow aid, improve storage and processing performance
Cosmetics/electronics – texture adjustment and dielectric property improvemen
