| Reaction properties In the presence of water (and a suitable catalyst such as acetic acid), CN-570 hydrolyzes its alkoxy groups to form methanol and active silanol groups, forming bonds on the surface of various inorganic substrates. Methacryloyl oxide can react with a suitable polymer. Suitable inorganic materials such as: glass, fiberglass, glass wool, mineral wool, silica, quartz, sand, cristobalite, wollastonite and mica; and aluminum hydroxide, kaolin, talc and other silicate fillers, metals and metal oxides Thing. Suitable resins include unsaturated polyesters, acrylic resins and vinyl resins. | ||||
| Storage conditions: Stored in the original unopened container at room temperature, this product has a shelf life of one year from the date of production, and expired products are tested. After passing, the buyer decides whether to continue to use it. | ||||
| Applications： CN-570 silane can increase the mechanical strength of the glass fiber yarn-reinforced composite material in the treatment of glass fiber yarn with a wetting agent containing, and can improve the wet and dry mechanical strength of polyester composites filled with silica, glass, silicate and metal oxides. CN-570 can improve the wet electrical properties of many inorganic filler filled composites. CN-570 can be copolymerized with vinyl acetate and acrylate or methacrylate monomers to synthesize silane-based polymers that can be cross-linked and cured at room temperature. These silylated polymers are widely used in coatings, adhesives and sealants. Provides excellent adhesion and durability. CN-570 silane can be applied to inorganic surfaces in the form of a diluted aqueous solution (0.1 to 0.5% silane). When preparing an aqueous solution, adjust the pH of the water to 3.0 to 4.5 with acetic acid, then add silane while stirring well. | ||||
