SiSiB® PC4300 is a methacryl-functional silane; it is a clear, light and heat sensitive liquid with a faintly sweet odour. It is equal to Dow's Z-6033, ShinEtsu's KBM-502.
SiSiB® PC4300 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.
SiSiB® PC4300 acyl silane China is the equivalent of Dow's Z-6033, ShinEtsu's KBM-502.
Solubility: SiSiB® PC4300 is soluble in methanol, ethanol, isopropanol, acetone, benzene, toluene, and xylene. After hydrolysis, it is soluble in water with adequate stirring if the pH is adjusted to 4.0. Hydrolysis releases methanol.
SiSiB® PC4300 shows copolymerization or grafting reactions when catalyzed by (organic) initiator systems, e.g. peroxides or by radiation (e.g. UV).
Application
SiSiB® PC4300 can improve strength as glass fiber size composite in reinforced polyester composites.
SiSiB® PC4300, the high quality silicone silane, can enhance initial and wet strength of reinforced polyester resin composites.
SiSiB® PC4300 can enhance the wet electrical properties of many mineral-filled and reinforced composites.
SiSiB® PC4300 crosslinked acrylic type resins can improve adhesion and durability of exterior silicone adhesives and coatings.
Packing and Storage
SiSiB® PC4300 is supplied in 25Kg plastic drum, 200Kg steel drum or 1000Kg IBC container.
In the unopened original container SiSiB® PC4300 has a shelf life of 9 months in a dry and cool place.
