Momentive SILQUEST HDTMS Silane Coupling Agent

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

Features Of Momentive SILQUEST HDTMS Silane Coupling Agent

  1. Surface Hydrophobization - Long alkyl chains (C16) impart water/oil repellency

  2. Process Adaptability - Low viscosity (0.889 g/cm³) for easy blending

  3. Thermal Stability - High flash point (165°C) suits high-temperature applications

  4. Multi-Substrate Compatibility - Bonds glass, metals, and polymers

  5. Eco-Efficiency - Halogen-free, low VOC emissions

Typical Applications Of Momentive SILQUEST HDTMS Silane Coupling Agent

  1. Anti-Fog Coatings - Glass surfaces with durable hydrophobicity

  2. Rubber Reinforcement - Silica-filled tires/shoe soles for wear resistance

  3. Cultural Relic Protection - Acid/freeze-thaw resistance for artifacts

  4. Textile Finishing - Fabric softness and water repellency
