Organic Slicon Steel Sheet Insulation Paint
Jul 16, 2024
Used as a protective layer on the outer surface of coils and windings of various motors and electrical appliances, as well as on the sealed outer shell, to improve moisture resistance, insulation, chemical corrosion resistance, arc resistance, and three protections (anti mold, moisture-proof, anti salt spray). Silicon steel sheet coating has the advantages of heat resistance, oil resistance, insulation, and prevention of eddy currents in the gaps between stacked silicon steel sheets. It can be divided into clear varnish and surface enamel, with two types: drying type and room temperature drying type. Drying type has superior performance, while room temperature drying type is generally used as insulation coating repair paint for electrical equipment.
Grind a portion of the resin solution with iron red and silver pigment to below 30 µ m, mix with the entire resin solution, and adjust the viscosity of the paint with toluene. Add the drying agent according to the amount before use, and use it after thorough mixing.Can be used for coating or repairing the ends, coils, armatures, motors, and electrical equipment of winding components that operate in climates with a working temperature of 180 ° C or tropical humid conditions.Coated on the surface of silicon steel sheets, it has the advantages of heat resistance, oil resistance, insulation, and preventing eddy currents in the gaps between stacked silicon steel sheets.
Application: Suitable for surface immersion coating of electrical appliances, motors, transformers, etc.
Coatings for organic silicon electrical components
(1) Coatings for resistors, capacitors, and other surfaces have advantages such as moisture resistance, heat resistance, insulation, resistance to temperature fluctuations, high mechanical strength of paint film, good adhesion, friction resistance, and stable insulation resistance.
Organic silicone insulation paint has excellent heat resistance and electrical insulation performance, but poor solvent resistance, mechanical strength, and bonding performance. Generally, a small amount of epoxy resin or heat-resistant polyester can be added to improve it. If the formulation process conditions are appropriate, it will not affect its heat resistance.
(2) Organic silicon high-temperature insulation protective paint for semiconductor components has high dielectric properties, high purity, limited harmful metal content, strong adhesion, good thermal stability, moisture resistance, and semiconductor protection. It is suitable for high temperature and high voltage places.
(3)Organic silicon insulation protective coating for printed circuit boards, integrated circuits, and solar cells has a tough paint film, good dielectric properties, weather resistance, UV resistance, dust pollution prevention, moisture resistance, room temperature drying, and strong light transmission. It is suitable for insulation protection of printed circuit boards, integrated circuits, and solar cells.
(4) Semiconductor contact coating
In semiconductor components, chips and contacts are extremely sensitive to impurities, dust, and moisture. Semiconductor contact paint (JCR) passivation and protection should be used in a timely manner, otherwise deviations and instability may occur. There are two types of commonly used contact coatings: hard coatings (condensed silicone resin) and soft coatings (including condensed and additive single component and two-component silicone rubber). Due to the direct application of contact coating on the surface of semiconductor chips, there are strict restrictions on harmful impurities. Ten years ago, it was required that the content of Na and K ions be less than 1000 x 10-6. Now, it is required that the content of Na, K, Fe, Cu, Pb, and Cl ions be less than 1000 x 10-6, while the content of U and Th ions should be less than 0.001 x 10-6.
