Silicone resin is a new material of modern industrial manufacturing, but also countries all over the world are vying to develop a material, silicone resin is widely used in high-tech fields, is one of the main raw materials, at the same time, it is also widely used in our daily life, which is mainly due to its properties.
Characteristics of silicone resin
1, heat-resistant
General anti-corrosion coating paint resistant to high temperature temperature of about 150℃, and silicone material paint can be used for a long time at 200℃. If the high temperature pigment is added, the high temperature resistance can reach 400℃~500℃, and the unique can also achieve 800℃~900℃. Therefore, it is suitable for coating heat resistant components.
2, electrical equipment characteristics and hate water number
Because the organic silicon material paint molecular structure surface layer has a layer of non-polar organic chemistry genetics and molecular structure of the symmetry, thus become its excellent insulating properties and hydrophobic basis. At the dielectric strength level, not only the grounding resistance is high, but also the penetration strength and the resistance to high piezoelectric spark discharge are mainly shown in the quality characteristics, so it can be used for prepreg motors and components with higher dielectric strength to improve the flame retardant level of the insulating layer components.
3, surface activity, small supporting force
Because polysiloxane has a symmetrical molecular structure and its functional groups are non-polar organic chemical groups, all chemical formulas are non-polar. The interaction between small molecular structure, molecular structure of its own cohesive force is small, so small interfacial tension, when its diversification in interfacial tension when a lot of material surface, can go to the material separation, and because of its molecular structure and material of the contact force is small, so it can reduce the interfacial tension of the material, it is not easy to produce foam. This is why methyl silicone oil can be used in paint demulsification effect, so it can be used as silicone defoamer and leveling agent in another paint, to avoid paint layer shiny, black spots, etc., the amount of 0.2%~0.3%.
