The performance of silicone resins depends not only on the composition of the organosilane mixture but also on the curing process. According to the mechanism of crosslinking curing reaction, it can be divided into three types:
★ Condensation cross-linking: Containing hydroxyl groups or other silicon functional groups, in-depth polymerization and cross-linking in the presence of heating or catalysts to form a three-dimensional network structure. It has the advantages of good adhesion, heat resistance, fast curing speed and low cost. Commonly used in coatings and adhesives for electronic components.
★ Platinum addition crosslinking: crosslinking by addition reaction of ≡Si-CH=CH2 group siloxane and ≡Si-H group siloxane in the presence of platinum catalyst. It has the advantages of good adhesion to the same substrate, excellent electrical properties, thermal shock resistance, and thermal conductivity. Commonly used in bushings, heat-resistant coatings, coil impregnation, laminates, adhesives, etc.
★ Peroxide cross-linking: Contains vinyl groups, which are cured into a spatial network structure under heating and peroxide initiation. It has the advantages of good electrical insulation, Waterproof, low-temperature curing, no solvation, and a long storage period. Commonly used in electronic component coatings.
