ST3202 Two-component Silicone for Electrical Insulation Potting
ST3202 is a two-component silicone, which is easy to use due to the mixing ratio A: B=1:1 . This product has good toughness and leveling. After mixing, it can be cured within 30 minutes at 80ºC, or it can be cured at room temperature.
Features and benefits
- Two-component silicone, mixing ratio 1:1
- Good leveling and good adhesion to many materials
- Lower curing with low volume shrinkage
- High temperature resistance
- Good weather resistance, aging resistance, non-yellowing
- Complying to the 2011/ 65/EU RoHS regulations.
