Momentive SILQUEST HDTMS (cetyltrimethoxysilane)Silane Coupling Agent interfacial compatibility between organic polymers (e.g., rubber, plastics) and inorganic substrates (e.g., glass, SiO₂) via its long alkyl chain and methoxy groups. It improves hydrophobicity, mechanical strength, and filler dispersion in coatings, adhesives, and composites. With rapid hydrolysis under acidic conditions, it complies with REACH standards, ideal for anti-fogging coatings and fiber-reinforced materials
Surface Hydrophobization - Long alkyl chains (C16) impart water/oil repellency
Process Adaptability - Low viscosity (0.889 g/cm³) for easy blending
Thermal Stability - High flash point (165°C) suits high-temperature applications
Multi-Substrate Compatibility - Bonds glass, metals, and polymers
Eco-Efficiency - Halogen-free, low VOC emissions
Anti-Fog Coatings - Glass surfaces with durable hydrophobicity
Rubber Reinforcement - Silica-filled tires/shoe soles for wear resistance
Cultural Relic Protection - Acid/freeze-thaw resistance for artifacts
Textile Finishing - Fabric softness and water repellency
