Silicone resin coatings have a variety of excellent properties, especially the modified coatings can better meet the requirements of architectural decoration.

Silicone insulating materials mainly include two categories, namely enamel and varnish. In the actual application process, it mainly includes two kinds of low temperature curing type and high temperature curing type. Based on the wide frequency range, its dielectric loss is relatively low, and the temperature change is not high. At this stage, for most silicone-modified epoxy esters, they are mainly liquid, making it difficult to meet the demand for powder coatings.

At present, some experts and scholars have modified epoxy resin with hydroxy silicone oil. After a series of experiments, they have successfully completed the modification work and made in-depth research on the electrical properties of silicone modified epoxy resin. Relevant research shows that when organosilicon is inserted into the epoxy resin chain, the relative molecular mass is 5,000 at this time. In addition, in the electrical performance test of the prepared coating film, through high-pressure cooking, it is finally found that it has higher electrical performance, which indicates that the resin can be used in insulating powder coatings.

Elastoplastic silicone "three-proof" material

At present, through the analysis of the comprehensive performance of all the "three-proof" materials, the elastic-plastic silicone "three-proof" material is the material with the best comprehensive performance. In the actual application process of elastoplastic silicone "three-proof" materials, they often have the characteristics of convenient construction and low-temperature curing. When the coating is cured, it not only has high-frequency dielectric properties, but also has the ability to withstand high and low temperature impacts. Elastoplastic silicone "three-proof" material is used as the copolymer of the block of silicone resin and linear polysiloxane. In the actual application process, linear polysiloxane is often used. And currently, this material can be prepared by co-condensation with different organosilicon monomers in the presence of solvents under the action of a catalyst. In addition, this material is a xylene solution with a resin content of 50% to 60%. Based on room temperature conditions, the material has good storage stability. If the catalyst is added to it, it can be cured into a film. With its own strong advantages, the material has been widely used in many fields of society, such as medicine, petroleum, electronics and other industries, and is mainly used for moisture-proof treatment of capacitors in these fields.
