Silicone resin is a thermosetting polysiloxane polymer with a highly cross-linked structure. It has the dual characteristics of organic resin and inorganic material. It has unique physical and chemical properties, good electrical insulation properties, temperature resistance and Waterproof effect. The weather resistance of silicone resin is better than that of general organic resin. Therefore, it is an ideal material for the coating of temperature-resistant, heat-resistant and moisture-proof treatment protective surface layers.

Silicone resin is mainly used as insulating paint (including varnish, enamel, paint, impregnating paint, etc.) to impregnate H-class motor and transformer coils, and to impregnate glass cloth, glass cloth and asbestos cloth to make motor bushings and electrical insulation. winding, etc. The large-area mica sheet insulating material can be obtained by bonding mica with silicone insulating paint, which is 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, construction waterproof and moisture-proof coatings, mold release agents, adhesives and secondary processing into silicone plastics for electronic, electrical and defense industries In the past, as semiconductor packaging materials and electronic and electrical silicone resins, it can be roughly divided into several categories such as silicone insulating paints, silicone coatings, silicone plastics and silicone adhesives according to their main uses and cross-linking methods. Silicone resin processing additives have unique flexibility and compatibility, and have become a key ingredient in pulp and tissue production. details as follows:

(1) Electrical insulating paint: The volume, quality and service life of electrical appliances have a great relationship with the performance of electrical insulating materials. Therefore, the industry requires the use of a variety of electrical insulating paints, including coil impregnating paint, glass cloth impregnating paint, mica adhesive insulating paint, and silicone paint for electrical and electronic protection.
(2) Coating: Silicone resin has excellent heat resistance, cold resistance, weather resistance, water repellency and other properties, and can obtain colorless and transparent coatings with good adhesion and wear resistance. coating.
(3) Adhesives: There are two types of polysiloxanes used as adhesives: silicone type and silicone resin type, which are different in structure and crosslinking density. Among them, resin type adhesives are also divided into pure silicone resin type and modified type resin.
(4) Plastics: mainly used in heat-resistant, insulating, structural, and arc-resistant silicone plastics, semiconductor component casing encapsulation plastics, and foamed plastics.
(5) Micropowder and trapezoidal polymer: Compared with inorganic fillers, silicone resin micropowder has low relative density, and also has the characteristics of heat resistance, weather resistance, lubricity and hydrophobicity. Trapezoidal silicone resin has higher heat resistance, electrical insulation and flame resistance than general-purpose mesh-shaped three-dimensional silicone resin.
