SiSiB® PC4100H is a methacryl-functional silane; it is a clear, light and heat sensitive liquid with a faintly sweet odour.
SiSiB® PC4100H acyl silane 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 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. Compared with SiSiB® PC4100, PC4100H is more clear, purity is higher, and Chloride is lower.
Solubility: SiSiB® PC4100H 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® PC4100H shows copolymerization or grafting reactions when catalyzed by (organic) initiator systems, e.g. peroxides or by radiation (e.g. UV).
SiSiB® PC4100H can improve strength as glass fiber size composite in reinforced polyester composites.
SiSiB® PC4100H, the high quality silicone silane, can enhance initial and wet strength of reinforced polyester resin composites.
SiSiB® PC4100H can enhance the wet electrical properties of many mineral-filled and reinforced composites.
SiSiB® PC4100H crosslinked acrylic type resins can improve adhesion and durability of adhesives and coatings.
SiSiB® PC4100H 3-methacryloxypropyltrimethoxysilane is specially designed as adhesion promoter in EVA encapsulant films for solar PV cells. SiSiB® PC4100H can easily be compounded into the EVA encapsulant film. SiSiB® PC4100H is an excellent solution to adhere the encapsulant to the glass substrates and front sheets.
