GC9076 Silane

GC9076 is a methacryl-functional silane, it is a clear, light and heat sensitive liquid with a faintly sweet odour.

GC9076 is used as adhesion promoter at organic/inorganic interfaces, as surface modifier(e.g. imparting water repellency, organophilic surface adjustment) or as corsslinking 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.
