Product introduction

YAC-O174 is a methacryl-functional silane; it is a clear, light and heat sensitive liquid with a faintly sweet odour. It is equal to Momentive's A-174, Dow's Z-6030, Wacker's GF31, Evonik's Dynasylan MEMO, ShinEtsu's KBM-503.

YAC-O174 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.


YAC-O174 3-methacryloxypropyltrimethoxysilane, MEMO silane, can improve strength as glass fiber size composite in reinforced polyester composites.

YAC-O174, the high quality silicone silane, can enhance initial and wet strength of reinforced polyester resin composites.

YAC-O174 can enhance the wet electrical properties of many mineral-filled and reinforced composites.

YAC-O174 crosslinked acrylic type resins can improve adhesion and durability of adhesives and coatings.
