Silicone adhesive is divided into silicone resin as the base material adhesive and room temperature vulcanized silicone rubber as the base material adhesive, the former is mainly used for bonding metal and heat-resistant non-metallic materials, the adhesive parts can be used in the temperature range of -60-120℃; The latter is mainly used for bonding heat-resistant rubber, rubber and metal and other non-metal materials.
Silicone resin is a cross-linked semi-inorganic polymer with silicon-oxygen-silicon as the main chain, and the silicon atoms are connected with organic groups. It is made of multi-functional silicone through hydrolysis and condensation, and can be further transformed into a three-dimensional structure of insoluble and non-melting thermosetting resin under the action of heating or catalyst. Organic silicone resin can be divided into methyl silicone resin, phenyl silicone resin, methyl phenyl silicone resin and so on according to the different connecting groups on silicon atoms.
