Waterborne high temperature resistant silicone resin is one of the many characteristics of silicone resin applications, it has some of the characteristics of silicone resin itself, such as high temperature resistance, water resistance, which is usually shown in two aspects of water-based silicone resin, in addition, what is it "outstanding"?
At present, when silicone resin is used as high and low temperature insulation paint and special paint, aromatic hydrocarbons, or alcohols are mostly used as organic solvents, which will produce a large amount of VOC (volatile organic compounds), which will cause a certain degree of impact on the environment and human body. Water-based silicone resin uses water as the solvent, so it has a good environmental protection. Compared with organic solvents, water-based silicone resins use water as a solvent, which has a safety characteristic. Organic solvents are flammable, and water-based products can effectively reduce the occurrence of fire. Waterborne silicone resin coating can maintain high adhesion with the substrate after film formation. The cured film has excellent corrosion resistance and chemical resistance, small shrinkage of the film, high hardness, good wear resistance and excellent electrical insulation performance.
Superabsorbent resin (water-retaining agent) series, but also has a very good role in retaining water. Water-based silicone resins are generally water-dispersed resin and water-emulsion resin. The difference between them lies in whether the emulsifier is added, or the proportion of emulsifier, and the hydrophilic group in the polymer chain. In some research experiments, people can judge according to the particle size of the polymerization dispersed in water, water dispersed resin particle size range is in 0.001-0.1μm, and the resin emulsion particle size is basically greater than or equal to 0.1μm; Or water-based resin emulsion particle size ≥1μm, resin dispersion particle size ≤1μm. The concept between the two is more vague, the boundary line is not clear. Generally speaking, the water-based silicone resin has good hydrophilicity, and the finished product configured has a high degree of environmental protection, stability, high temperature resistance, insulation, high hardness after film formation, storage and transportation are relatively safe, and can be applied to a variety of different environments.
