Second, silicone coatings maintain their insulation properties over a wide temperature range. Due to the high-temperature resistance of silicone, it can still maintain stable electrical insulation properties in high-temperature environments. Even at high temperatures above 200°C, the dielectric constant and dielectric loss of silicone resin coatings remain at a low level. This feature makes silicone resin coatings widely used in electrical equipment that requires high temperature resistance, such as aerospace, power electronics and other fields.
