Reaction characteristics of Co-Formua Silane Coupling Agent CFS-838

The hydrolysis of this product requires an organic acid (such as formic acid, acetic acid, etc.) as a catalyst. Specifically, the pH value of the water is adjusted to about 4, and then silane is added and stirred for a period of time (at least 15 minutes) until the silane is completely dissolved and the solution is clear and transparent. . The hydrolysis rate is higher than that of ethyl silane, and its hydrolyzed product is unstable. It is recommended to use it up within 24 hours. If the solution is fogged, it means that the silane has partially self-polymerized to form a silane polymer (silicon) and fails.

Inorganic materials suitable 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. It is basically ineffective for fillers that do not contain hydroxyl groups on the surface, such as calcium carbonate, graphite, carbon black, and barium sulfate.

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