Highly hydrophobic surface treated with dimethyldichlorosilane for superior moisture resistance.
Optimized specific surface area (~100 m²/g) for balanced reinforcement and flowability.
Low density and excellent dispersion capability in non-polar systems including silicone elastomers and adhesives.
Consistent particle morphology and batch-to-batch reproducibility ensured by controlled flame hydrolysis synthesis.
Free-flowing powder with low dust generation, supporting safe and efficient handling in industrial processes.
Thixotropic agent in high-performance RTV and HTV silicone rubber compounds.
Reinforcing filler in solvent-based and high-solids coatings for improved sag resistance.
Viscosity stabilizer in adhesives and sealants based on polyurethane and polysulfide chemistries.
Anti-settling additive in liquid lubricants and greases requiring long-term storage stability.
Free-flow aid in pharmaceutical and food-grade powder blends (when compliant with applicable regulations).
