Alcohol-soluble silicone resin SH-9503
Ⅰ Properties & Uses
This product is a colorless transparent organic silicone resin ethanol solution which is formed by condensation of polyfunctional silicone monomer. The cured film is hard and transparent, has good insulation performance, friction resistance, heat resistance, aging resistance, radiation resistance shooting, not easy to embrittlement under low temperature, hydrophobic, moisture-proof, strong transmittance and other advantages. It can be used as hardening coating of transparent plastic such as organic glass (PMMA) , polycarbonate (PC), and glazing coatings of paper and ceramic.
It can also be used as insulating encapsulation coatings of electronic and electrical components under high temperature and high humidity conditions such as high frequency line circle.
At the same time, it can be used as protective coatings of all kinds of metalwork and decorative materials, to improve their wear resistance, aging resistance, water resistance, UV resistance and corrosion resistance.
