Highly pure, hydrophilic fumed silica with controlled particle size distribution for consistent rheology control.
Excellent thixotropic performance in liquid systems without compromising transparency or clarity.
Low abrasivity and high dispersibility, enabling smooth incorporation into sensitive formulations.
Stable viscosity enhancement across wide temperature and pH ranges in aqueous and solvent-based systems.
Low residual surface silanol density, minimizing unwanted side reactions in reactive resins and adhesives.
Thickening and anti-settling agent in water-based paints and architectural coatings.
Rheology modifier in UV-curable inks and overprint varnishes.
Viscosity stabilizer in silicone sealants and RTV elastomers.
Anti-sag additive in industrial maintenance coatings and marine primers.
Reinforcing filler in high-clarity silicone gels and optical encapsulants.
