SCA-R74P is a methacryloxysilane, which has a methacryloxysilane functional group with an unsaturated double bond structure and three hydrolyzable alkoxy groups (isopropoxy groups) , this dual reactivity allows them to improve their adhesion, adhesion and compatibility through bidirectional chemical reactions with inorganic materials (glass, metals, fillers) and organic polymers (thermosetting resins, plastics, elastomers) , the mechanical properties of the resin matrix composite or the adhesive strength and water resistance of the resin coating can be improved. The product can also be copolymerized with monomers such as acrylic acid, methacrylic acid acid, vinyl acetate and styrene containing unsaturated double bonds, thus, the copolymer is given moisture curing and good adhesion and water resistance. In different applications, they can be used as coupling agent, adhesion promoter, cross-linking agent, pigment and filler surface modifier, silicone modified graft copolymer, etc. . SCA-R74P is triisopropyl silane, its hydrolysis rate is slower than that of trimethoxysilane SCA-R74M, the side reaction of its hydrolysis is isopropanol, good environmental protection. The inorganic materials suitable for this product include silicon materials such as glass, glass fiber, glass wool, mineral wool, mica, quartz, Aluminum hydroxide, Magnesium hydroxide, kaolin, talc powder, metals such as steel, zinc, aluminum and their oxides, but on the calcium carbonate, graphite, carbon black, barium sulfate and other surfaces without hydroxyl fillers have no effect. Suitable polymers for this product include (but are not limited to) unsaturated polyester resins, peroxide vulcanized rubber such as EPR, EMDP, silicone rubber, SBR, natural peroxide vulcanized rubber, peroxide crosslinked plastics such as PE, PVC, etc.
