Momentive A-2120 Silane Coupling Agent

Momentive A-2120 (N-(β-aminoethyl)-γ-aminopropylmethyldimethoxysilane) is a diamino-functional silane coupling agent that enhances adhesion between organic resins (e.g., epoxy, polyurethane) and inorganic substrates (e.g., glass, metals). It improves mechanical strength, water resistance, and chemical stability in composites, coatings, and adhesives. Compatible with solvent/water-based systems, it enables rapid curing at ambient temperatures while complying with REACH standard

Features Of Momentive A-2120 Silane Coupling Agent

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

  2. Wet Adhesion - Maintains >90% bond strength after water immersion

  3. Process Efficiency - Lowers viscosity for easier filler dispersion

  4. Multi-Matrix Compatibility - Effective with epoxy, phenolic, and polyurethane resins

  5. Sustainability - Halogen-free, suitable for eco-friendly formulations

Typical Applications Of Momentive A-2120 Silane Coupling Agent

  1. Foundry Coatings - Reduces resin usage in phenolic-coated sand cores

  2. Textile Softeners - Amino-silicone oils for breathable fabrics

  3. Structural Adhesives - Enhances bonding to glass/aluminum in sealants

  4. Composite Reinforcement - Glass fiber sizing for FRP strength

  5. Anti-Corrosion Coatings - Improves metal substrate adhesion
