In the existing heat resistant adhesive, silicone adhesive is one of the excellent varieties, silicone adhesive varieties are divided into high temperature resistant adhesive, heat resistant sealant, high temperature resistant strain adhesive and heat resistant pressure sensitive adhesive. So, what are the applications of silicone adhesives?
Polysiloxane (polysiloxane) is a linear polymer composed of alternating silicon and oxygen atoms. After crosslinking and curing, it has excellent high and low temperature resistance, atmospheric aging resistance, electrical insulation and elasticity. It can be used in the range of -60 ~ 200℃ for a long time, and its physical and mechanical properties rarely change, so it is widely used in construction, electronics, automobile, packaging, medical and health industries, showing excellent development momentum. The use of silicone adhesives and sealants is expanding, varieties and dosage are also increasing year by year.
The siloxane in the silicone resin can react with the compound containing the matrix, such as epoxy, phenolic and poly, so these compounds can be used to modify the silicone adhesive.
