Highly pure, pyrogenically produced silica with low sodium and chloride content.
Optimized surface chemistry for efficient thickening and rheology control in non-aqueous systems.
Consistent particle size distribution ensuring reproducible dispersion performance.
Low oil absorption value enabling high loading capacity without excessive viscosity build-up.
Excellent thixotropic recovery for improved sag resistance and application stability.
Thickener and anti-settling agent in solvent-based coatings and industrial paints.
Rheology modifier in reactive resins including epoxy, polyurethane, and unsaturated polyester systems.
Reinforcing filler and viscosity stabilizer in silicone elastomers and RTV sealants.
Free-flow aid and anti-caking agent in specialty powder formulations.
Stabilizer in lithium battery electrolyte gels and cathode slurries.
