Highly pure, pyrogenically produced silica with low surface hydroxyl density.
Optimized for rheology control and anti-settling performance in non-aqueous systems.
Consistent particle morphology and narrow primary particle size distribution (~7 nm).
Excellent dispersibility in polar organic solvents and reactive resins.
Low sodium and heavy metal content, supporting high-performance electronic and coating applications.
Thixotropic agent in high-solids coatings and industrial maintenance paints.
Rheology modifier in UV-curable inks and digital printing formulations.
Reinforcing filler and viscosity stabilizer in silicone elastomers.
Anti-sag additive in adhesives and sealants for construction and automotive assembly.
Performance enhancer in battery electrolyte gels and specialty composites.
