What is organic silicone resin? Many people don't have that much understanding of organic silicone resin yet. In fact, organic silicone resin has applications in many aspects. Next, organic silicone resin manufacturers will take you to learn about organic silicone resin and take a look together.

It is a highly cross-linked network structure of polyorganosiloxanes, usually composed of various mixtures of methyltrichlorosilane, dimethyldichlorosilane, phenyltrichlorosilane, diphenyldichlorosilane, or methylphenyldichlorosilane. In the presence of organic solvents such as toluene, it is decomposed with water at lower temperatures to obtain acidic hydrolysates. The initial product of hydrolysis is a mixture of cyclic, linear, and cross-linked polymers, typically containing a considerable amount of hydroxyl groups. The hydrolysate is washed with water to remove the acid, and the neutral initial condensate is thermally oxidized in air or further condensed in the presence of a catalyst, ultimately forming a highly cross-linked three-dimensional network structure

Organic silicone resin is mainly used as insulation paint (including varnish, enamel, color paint, impregnation paint, etc.) to impregnate H-grade motor and transformer coils, as well as to impregnate glass cloth, glass cloth wire, and asbestos cloth to make motor sleeves, electrical insulation windings, etc. Large area mica sheet insulation material can be prepared by bonding mica with organic silicon insulation paint, which can be used as the main insulation of high-voltage motors. In addition, silicone resin can also be used as heat-resistant and weather resistant anti-corrosion coatings, metal protective coatings, waterproof and moisture-proof coatings for construction projects, release agents, adhesives, and secondary processing into organic silicon plastics, used in electronics, electrical, and national defense industries, as semiconductor packaging materials and insulation materials for electronic and electrical components.

There are roughly three ways to cure and crosslink silicone resin: one is to use hydroxyl groups on silicon atoms for condensation polymerization and cross-linking to form a network structure, which is the main method adopted for silicone resin curing; the other is to use vinyl groups connected to silicon atoms, using organic peroxides as catalysts, similar to silicone rubber vulcanization; the third is to use vinyl groups connected to silicon atoms and silicon hydrogen bonds for addition reactions, For example, solvent-free silicone resin can be mixed with foaming agent to produce foam silicone resin. Therefore, silicone resins can be roughly divided into several categories based on their main uses and cross-linking methods, including silicone insulation coatings, silicone coatings, silicone plastics, and silicone adhesives.
