Of course, the high temperature resistant coating resin matrix first considers the high temperature resistant resin, but also needs to take into account the excellent adhesion performance of the resin, low viscosity, good process performance, toughness and price and other properties, the actual choice of resin is not much. Epoxy is not high temperature resistant; RVS silicone rubber has low strength and high viscosity. Modified bisequine resin has high price and viscosity. Silicone resin has excellent high temperature resistance, but poor adhesion. References at the end of the 1, the author adopted by epoxy resin and reactive silicone oligomer by chemical modification of epoxy modified silicone resin as a coating of high temperature polymer matrix, the excellent uf resin with epoxy resin performance, high strength and excellent resistance to high temperature of organic silicon, as well as excellent electric insulation performance, moreover also has low viscosity, good manufacturability, Epoxy curing agent can be used for room temperature or medium temperature curing, easy construction, curing resin mechanical properties are good. The study shows that the resin has the advantages of moisture resistance, weather resistance, water resistance, salt water resistance, oil resistance, temperature resistance, moisture resistance, electrical insulation, good adhesion, nuclear radiation resistance and wave permeability under the appropriate formulation and process conditions. Therefore, epoxy modified silicone resin is a suitable substrate for high temperature coating.
