Silicone resin adhesive application analysis

What is a silicone adhesive? Silicone resin adhesive application analysis
In the existing heat-resistant adhesive, silicone adhesive is one of the excellent varieties, silicone adhesive varieties are resistant to high temperature adhesives, heat-resistant sealants, high-temperature strain adhesive and heat-resistant pressure-sensitive adhesives and so on. So, what are the applications of silicone adhesives?
polysilicon oxane is a linear polymer composed of silicon and oxygen atoms alternately, and after cross-linking vulcanization, it has excellent resistance to high and low temperatures, atmospheric aging, and electrical insulation and elasticity. Can be used in the range of -60 to 200 degrees C for a long time, its physical mechanical properties rarely change, so widely used in construction, electronics, automotive, packaging, medical and health care and other industries, showing excellent momentum of development, silicone adhesives and sealants continue to expand the use of varieties and dosages are also increasing by
silica in silicone resins can react with mesoplastic compounds such as epoxy, phenolic aldehydes, and polycodone, so these compound resin modified silicone adhesives can be used.
silicone resin
pure silicone resin as the main material of silicone adhesive, generally to xylene as a solvent, add inorganic fillers, such as asbestos powder, mica powder, chin dioxide and zinc oxide made. It is cross-linked polymerization at high temperature (270 degrees C), has excellent high temperature resistance, can be used at 400 degrees C for a long time, suitable for high temperature non-structural glue and sealing.
pure silicone adhesive due to high curing temperature and inconvenience, bonding strength is not high, can only be used as non-structural glue. Using epoxy, phenolic aldehyde, polyaminate in an OH and silicone resin silicone reaction introduced into such resins to modifie, can not only maintain the high temperature resistance of silicone adhesive, but also reduce its curing temperature and improve the strength of the glue.
silicone resin can be used in roller anti-stick jacket, widely used in the textile industry, printing and dyeing industry, paper industry, rubber processing, plastic processing and other fields of rollers, molds, pipes, engine walls, food machinery, printing machinery hopper, frying pan baking tray anti-stick coating, anti-rust and slip coating of the safety knife. Fluorine resin non-stick coating and silicone resin non-stick coating comparison: the former has the disadvantages of high curing temperature, complex construction process, low coating gloss, single color, so the application range is limited; Of course, fluorine non-stick coatings have a slight advantage over silicone non-stick coatings in terms of non-stick coatings.
