1、Heat resistance

General anti-corrosion paint paint high temperature resistance temperature of about 150 ℃ the following, and silicone material paint can be in 200 ℃ under long-term application. If add high temperature pigment, high temperature resistance reaches 400℃~500℃, unique can also do 800℃~900℃. Therefore, it is suitable for coating heat-resistant components.

2, electrical equipment characteristics and water-repellent number

Because the surface layer of the molecular structure of the silicone material paint with a layer of non-polar organic chemical genes and the symmetry of the molecular structure, thus becoming the basis of its excellent insulating properties and water-repellent reason. At the level of dielectric strength, it not only has high grounding resistance, but also shows quality characteristics in penetration strength and resistance to high voltage spark discharge, etc. Therefore, it can be used for pre-impregnated motors and components with high dielectric strength to improve the flame retardancy of the insulating components.

3、Large surface layer activity, small support force

Because polysiloxane is a symmetrical molecular structure, functional groups are also non-polar organic chemical functional groups, and thus all chemical formula non-polar. The interaction force between molecular structure is small, the bonding force of molecular structure itself is also small, so the interfacial tension is small, when it is dispersed in the surface layer of the material which has a large interfacial tension, it can separate the material to go, and because of its own and the molecular structure of the material between the interaction force is also small, so it can reduce the interfacial tension of the material, so that it is not easy to produce foam. This is the methyl silicone oil can be used in the manufacture of paint to play a role in breaking the emulsion effect of the reason, therefore, can be another paint as silicone defoamer, leveling agent, to avoid the paint layer shiny, black spots, etc., the amount of use of 0.2% to 0.3%.

4, good cold resistance

Because of the structure of silicone material paint biological macromolecules themselves, the molecular structure of the middle of the temptation is poor, so that it is granted to have excellent cold resistance. Pure silicone material cold resistance is -50 ℃ up and down, and polyester modified material silicone material paint W31-1 can withstand -80 ℃ the following temperature, therefore, this paint can be applied in the colder areas.

5、Excellent chemical resistance

Because of the storage of aldehyde in the silicone material paint, the original excellent chemical resistance. For example, the paint layer immersed in 2% glacial acetic acid: 10% sulfuric acid, 10% sodium cyanide, 10% hydrochloric acid, 10% sodium hydroxide, 10% sodium nitride or butanol, gasoline, after 100h, the paint layer is still excellent.

6、Excellent mold removal

Because of the silicone material paint does not have the component of oil, thus Aspergillus flavus can not survive in the silicone material paint layer, so that the silicone material paint has a good mold removal properties, suitable for coating in the unique mold removal provisions of the components.
