Product introduction

YAC-O174P is a methacryl-functional silane; it is a clear, light and heat sensitive liquid with a faintly sweet odour.

YAC-O174P 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 YAC-O174, YAC-O174P is more clear, purity is higher, and Chloride is lower.


YAC-O174P can improve strength as glass fiber size composite in reinforced polyester composites.

YAC-O174P, the high quality silicone silane, can enhance initial and wet strength of reinforced polyester resin composites.

YAC-O174P can enhance the wet electrical properties of many mineral-filled and reinforced composites.

YAC-O174P crosslinked acrylic type resins can improve adhesion and durability of adhesives and coatings.

YAC-O174P 3-methacryloxypropyltrimethoxysilane is specially designed as adhesion promoter in EVA encapsulant films for solar PV cells. YAC-O174P can easily be compounded into the EVA encapsulant film. YAC-O174P is an excellent solution to adhere the encapsulant to the glass substrates and front sheets.
