Reaction characteristics
When used as a coupling agent, CFS-282 [CAS 120218-28-2]hydrolyses its methoxy in the presence of water to form a reactive silicone hydroxyl group. This is accompanied by the release of methanol as a by-product of the hydrolysis reaction. This silicone hydroxyl group will react with the hydroxyl group on the surface of various inorganic materials (substrates or fillers) to form a chemical bond, while its amino group will react chemically or physically with a suitable polymer.
Suitable inorganic materials for this product include glass, glass fibre, glass wool, mineral wool, siliceous materials such as mica and quartz, and metals and their oxides such as aluminium hydroxide, magnesium hydroxide, kaolin, talc, steel, zinc and aluminium, but it is largely ineffective on fillers that do not contain hydroxyl groups on their surface such as calcium carbonate, graphite, carbon black and barium sulphate.
Suitable polymers for this product include (but are not limited to) phenolic, epoxy, furan, urea-formaldehyde, polyurethane, acrylic, polyester, silicone, nitrile and other thermosetting resins and plastics such as nylon, polycarbonate, PBT, PET, EVA, modified PP, PVC, PVB, PVAC and PS.
