Features
Heat Resistance
Siloxane bonds (Si-O-Si) form the backbone of the molecular structures of silicone resins. Siloxane bonds have high bonding energy and the temperature of thermal decomposition is high, so these resins have excellent heat resistance. There is typically no decomposition, degradation, or discoloration even in high-temperature conditions of 250°C or more.
Electrical Insulative properties
Silicone resins exhibit excellent electrical properties over a wide temperature range. In particular, even at high temperatures there is little decline in electrical insulative properties, and good resistance to arcing.
Weather Resistance
They exhibit outstanding weather resistance, with little degradation caused by UV rays or other elements. Coatings exhibit little yellowing, chalking, or loss of gloss, and they maintain stable coating properties over long periods.
Water Repellency
Due to the orientation of the methyl groups in the molecules, the surface of the cured material has excellent water repellency.
High Hardness
Silicone resins are highly branched 3-dimensional polymers, and the backbone structure of the cured material is similar to that of glass, so these materials can be used to modify surfaces to make them inorganic substances.
