         Electronic equipment, silicone rubber is a two-component RTV silicone rubber, can be used in direct contact with the metal as an insulating material, are also available in electronic and telecommunication equipment and instrumentation, pouring, insulation, shockproof, moisture-proof seal as packaging material. When used with a vulcanized dosages to control the operation time and the curing rate of this kind of grade RTV silicone rubber based polymer in preparation, selection must be strict control of low molar mass, volatile content of D3~D20, in order to avoid open electric contact near or closed, semi closed type electric device when in use, due to the containing volatile low-molecular polysilane cause the contact fault. The fillers, additives should be clean, to make vulcanized rubber electrical performance is ensured. Reduce the reinforcing filler thickening phenomenon and the prepared material in storage in the stable performance.

         Condensation type bicomponent RTV silicone rubber when in use, base material and curing agent are mixed according to a certain proportion, at room temperature will gradually thickening, finally vulcanized elastomers.Vulcanization rate can be vulcanized agent to control. In the curing agent and the dosage of constant, increase the thermometer increase environmental humidity can speed up the curing rate, shorten curing time. In general, the base material is mixed with the curing agent in 5 of the following can be stored a long time; heating can promote sulfide, but not more than 80 degrees, due to the high temperature adhesive surface crosslinking agent volatile lead stickness.

          Electronic equipment silicone rubber for insulation, shockproof, moisture-proof perfusion and fillers, and other insulating material, has good electrical properties, characteristics of dielectric constant, dielectric loss tangent and dielectric properties than other materials are small, and the frequency and temperature stability, corona resistance, arc resistance.
