3-Methacryloxypropyltrimethoxysilane
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.
Technical Data
Application
Improve the mechanical properties of composite materials: Using in unsaturated polyester composite material, can improve the mechanical property of the composite materials such as enhancing strength, improving toughness, especially can significantly improve the wet performance of the composite material.
Use in artificial quartz stone and agglomerated stone. In agglomerated stone, it process the surface treatment to the resin, which can significantly improve the tensile strength, bending strength, and bending modulus of elasticity of the artificial quartz stone and the agglomerated stone, also have great assistance to the anti-dirty ability and anti-foaming property of the product.
Improve the flexible property and its physical and mechanical properties. Reinforce the filler's dispersing capacity in the resin system, also its water resistance, stain resistance, moisture resistant performance. Also with good permeability& wettability. Anti-foaming property & coupling effects.
Packing and Storage
Storage: Keep away from open flames, hot surfaces and sources of ignition. Keep container tightly closed.
Recommend Shelf Life: 12 months.
