SiSiB® PC4200 is a methacryl-functional silane; it is a clear, light and heat sensitive liquid with a faintly sweet odour. It is the equivalent of Momentive's Y-11878, Dow's Z-6036, Wacker's GF32, ShinEtsu's KBE-503.
SiSiB® PC4200 acyl silane is used as adhesion promoter at organic/inorgainc interfaces, as surface modifier. 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 silicon based polymers, including polyolefins and polyurethanes. It is also used to functionalize resins via radical initiated processes - copolymerization or grafting - and to modify surfaces.
