Momentive SILQUEST A-1128 Silane Coupling Agent

Momentive SILQUEST A-1128 is an aromatic-modified polyaminoalkyl silane coupling agent, engineered to enhance adhesion between epoxy/polyamide resins and glass fibers or inorganic fillers. It optimizes interfacial bonding, chemical resistance, and mechanical strength in composites, while enabling rapid curing at ambient temperatures. Ideal for fiber-reinforced materials and electronic laminates, it complies with REACH standards for sustainable industrial use

Features Of Momentive SILQUEST A-1128 Silane Coupling Agent

  1. Hybrid Reactivity - Aromatic-amino groups bond with resins; methoxy links to glass/fillers

  2. Process Efficiency - Lowers viscosity for improved fiber wet-out and dispersion

  3. Thermal Stability - Maintains performance in high-temperature applications (e.g., circuit boards)

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

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

Typical Applications Of Momentive SILQUEST A-1128 Silane Coupling Agent

  1. FRP Composites - Glass fiber sizing for epoxy/polyamide reinforcement

  2. Electronic Laminates - Surface treatment for circuit board fiber cloth

  3. Industrial Sealants - Polysulfide/polyurethane systems with enhanced wet adhesion

  4. Anti-Corrosion Coatings - Metal primers with improved chemical resistance
