In the presence of water, the alkoxy group of CFS-043 cas 3388-04-3 [A-186; KBM-303; Z-6043] will be hydrolyzed to form an active silicone hydroxyl group, while releasing methanol 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, while its epoxy group can be subjected to heat or acid or alkali catalyst to epoxy ring-opening reaction and chemical reaction with suitable polymers (containing primary amino group, hydroxyl group, carboxyl group, epoxy group, anhydride, etc.), through the above-mentioned two-way reaction this product can realize the coupling between inorganic fillers (or substrates) and Through the above two-way reaction, this product can realize the coupling and connection between inorganic filler (or base material) and organic polymer material. 

The hydrolysis of CFS-043 cas 3388-04-3 [A-186;KBM-303;Z-6043] requires the use of organic acids (such as formic acid, acetic acid, etc.) as catalysts, specifically by adjusting the pH of water to about 4, then adding silane and stirring for a period of time (at least 15 minutes) until the silane is completely dissolved and the solution is clear and transparent. Its hydrolysate is unstable, so it is recommended to use it up within 24 hours. The solution fogging means that the silane has partially self-polymerized to form the polymer of silane (silicone) and failed. The product can be emulsified with appropriate emulsifiers for use in aqueous systems, and some alcohol solvents can be used as co-solvents to improve its water solubility and stability in water.
Suitable inorganic materials for this product include glass, glass fiber, glass wool, mineral wool, mica, quartz and other siliceous materials and aluminum hydroxide, magnesium hydroxide, kaolin, talc, steel, zinc, aluminum and other metals and their oxides, but it is basically ineffective for fillers that do not contain hydroxyl groups on the surface such as calcium carbonate, graphite, carbon black, barium sulfate, etc.

Suitable polymers for this product include (but not limited to) phenolic, epoxy, urea-formaldehyde, polyurethane, acrylic, polyester, silicone, polysulfide, PVAC and other resins and nylon, PBT, PET and other plastics.
