Momentive SILQUEST A-1387 (γ-glycidoxypropyltrimethoxysilane) enhances adhesion between organic resins (e.g., acrylics, epoxies) and inorganic substrates (e.g., glass, metals) via its epoxy and methoxy groups. It improves mechanical strength, wet adhesion (>90% retention), and chemical resistance in coatings, adhesives, and composites. Compatible with water-based systems, it reduces VOC emissions and complies with REACH standards, ideal for leather coatings and glass treatments
Dual Reactivity - Epoxy bonds with resins; methoxy links to fillers/metals
Wet Adhesion - Maintains >90% bond strength after humidity exposure
Process Efficiency - Lowers viscosity for easier filler dispersion
Multi-Matrix Compatibility - Works with water-based and solvent-based resins
Sustainability - Halogen-free, low VOC (<50 g/L)
Leather Coatings - Enhances wet rub resistance and high-temperature durability
Waterborne Coatings - Improves adhesion in carboxyl-containing resin systems
Glass Treatments - Boosts resin adhesion and coating hardness on glass substrates
Structural Adhesives - Strengthens bonding in epoxy/polyurethane systems
