Momentive SILQUEST A-1106 Aminosilane Coupling Agent

Momentive SILQUEST A-1106 is an amino-functional silane coupling agent that enhances adhesion between organic resins (e.g., epoxy, polyurethane) and inorganic substrates (e.g., glass, metals) via its amine and methoxy groups. It improves mechanical strength, wet adhesion (>90% retention), and filler dispersion in coatings, adhesives, and composites. Compatible with water-based systems, it reduces VOC emissions and complies with REACH standards

Features Of Momentive SILQUEST A-1106 Aminosilane Coupling Agent

  1. Dual Reactivity - Amino groups bond with resins; methoxy links to fillers/metals

  2. Wet Adhesion - Maintains >90% bond strength after humidity exposure

  3. Process Efficiency - Alcohol-free aqueous solution for safer handling

  4. Multi-Matrix Compatibility - Works with epoxy, PU, and phenolic resins

  5. Sustainability - Halogen-free, low VOC (<50 g/L)

Typical Applications Of Momentive SILQUEST A-1106 Aminosilane Coupling Agent

  1. Waterborne Coatings - Enhanced metal/glass adhesion for anti-corrosion coatings

  2. Structural Adhesives - Improved bonding in PU/epoxy systems

  3. FRP Reinforcement - Glass fiber sizing for high-strength composites

  4. Rubber Compounding - Silica-filled EPDM for cables and seals
