Characteristic
Excellent heat resistance
- Typically no decomposition, degradation or discoloration even in high temperature conditions of 250°C or more
Electrical insulative properties
- Excellent electrical properties over a wide range of temperatures.
Weather resistance
- Excellent weather resistance with little degradation caused by UV rays or other elements.
Water repellency
- Due to the orientation of the methyl groups in the molecules, the surface of the cured materials has excellent water repellency.
High hardness
- These materials can be used to modify surfaces to make them inorganic substances
