In the presence of water, the alkoxy group of CFS-S070 cas 17096-07-0 is hydrolyzed to form an active silicone hydroxyl group, which releases trimethylsilanol as a by-product of the hydrolysis reaction. This silicone hydroxyl group will be condensed with the hydroxyl group on the surface of various inorganic materials (substrates or fillers) to form a chemical bond; and its methacryloyl group can be copolymerized with other monomers containing unsaturated double bonds such as acrylic acid, methacrylic acid, vinyl acetate, styrene, etc. under the action of heat or peroxide initiation, or under the action of peroxide initiation with the newly initiated unsaturated double bonds on plastics, rubber or resins. The product can be fully or partially cross-linked and cured by the addition reaction with the newly initiated unsaturated double bond on the plastic, rubber or resin under the action of peroxide initiation. Through the above two-way reaction, this product can realize the coupling and linking between inorganic fillers (or substrates) and organic polymer materials, or realize the silanization grafting modification or cross-linking of resins.
The hydrolysis of CFS-S070 cas 17096-07-0 requires organic acids (such as formic acid, acetic acid, etc.) as catalysts, specifically by adjusting the pH of water to about 3.5~4.5, then adding silane and stirring for a period of time (at least 30 minutes or more) until the silane is completely dissolved and the solution is clear and transparent. Their hydrolysates are unstable and it is recommended to use them up within 24 hours. Fogging of the solution means that the silane has partially self-polymerized to form a polymer of silane (silicone) and failed.
Its aqueous solution can significantly reduce the surface energy, e.g. 0.9% of CFS-S070 cas 17096-07-0 silane aqueous solution can reduce the surface energy by about half from 72 dynes/cm. This indicates that the hydrophobic organic part of the silane forms an oriented layer at the gas/liquid interface.
When treating mineral fillers, the minerals can be co-mingled with the silane at high shear rates without the addition of any solvent. After treating the silane, the treated substrate or mineral surface should be dried briefly at 104 to 121°C to allow the silanol to complete condensation and to remove the small amount of methanol or ethanol formed during hydrolysis of the methoxysilane.
Suitable polymers for this product include (but are not limited to) unsaturated polyester resins, peroxide-cured rubbers such as EPR, EMDP, silicone rubber, butadiene, natural and other peroxide-cured rubbers, and peroxide-cross-linked plastics such as PE and PVC.
