GX-570 Silane Coupling Agent

3-Methacryloxypropyltrimethoxysilane is a methacryl-functional silane, it is a clear, light and heat sensitive liquid with a faintly sweet odour.
3-Methacryloxypropyltrimethoxysilane is used as adhesion promoter at organic/inorgainc interfaces, as surface modifier (e.g. imparting water repellency, organophilic surface adjustment) or as crosslinking of polymers).

It is used as a coupling agent to improve the physical and electrical properties of glass-reinforced and mineral-filled thermosetting resins under exposure to heat and/or moisture.

It is typically employed as a blend additive in resin systems that cure via a free radical mechanism (e.g. polyester, acrylic) and in filled or reinforced thermoplastic polymers, including polyolefins and polyurethanes.

It is also used to functionalize resins via radical initiated processes – copolymerization or grafting – and to modify surfaces.

Applications:

• • 3-Methacryloxypropyltrimethoxysilane can improve strength as glass fiber size composite in reinforced polyester composites.
  • Enhance initial and wet strength of reinforced polyester resin composites.
  • Enhance the wet electrical properties of many mineral-filled and reinforced composites.
  • Crosslinked acrylic type resins can improve adhesion and durability
