What is a silicone resin? Silicone resins are semi-inorganic and semi-organic polymers with -Si-O- as the main chain and organic groups in the side chain. Silicone resin is a bulk polymer with multiple active groups, and these active groups are further cross-linked, that is, converted into an insoluble and infusible three-dimensional solidified product.

Silicone resin has excellent properties such as high and low temperature resistance, weathering resistance, water and moisture resistance, high dielectric strength, low dielectric loss, arc resistance, and radiation resistance.

General-purpose solution-type silicone resins are mainly used as base polymers for heat-resistant coatings, weather-resistant coatings and high-temperature electrical insulating materials.

Among all kinds of silicone polymers, silicone resin is the first type of silicone product to be synthesized and applied. Compared with the rapid development of silicone rubber pattern renovation technology, the technical improvement of silicone resin is relatively slow, and there are few major technological breakthroughs. . Beginning about two decades ago, due to the technological progress of aromatic heterocyclic heat-resistant polymers, some applications originally belonged to silicone resins have been squeezed. However, the solvent toxicity and harsh curing conditions of aromatic heterocyclic heat-resistant polymers The expansion of applications is limited. In recent years, people have begun to pay attention to the research and development of silicone resins. Silicone resins have outstanding advantages such as wide temperature range, aging resistance, and good hydrophobicity and moisture resistance. development space.
