ELASTOSIL® LR 3675/30 A/B
- Chemical Family
- Silicones
ELASTOSIL® LR 3675/30 A/B is a self-adhesive liquid silicone rubber of the ELASTOSIL® LR 3675 series. It is a paste-like, easily pigmentable, two-component compound with a short curing time and a low coefficient of friction. In comparison with ELASTOSIL® LR 3070 grades, the coefficient of friction is reduced by 50-70%. The vulcanizates are noted for their excellent mechanical and electrical properties. Due to the low compression set, there is no need to post-cure finished parts.

- Properties
ELASTOSIL® LR 3675 series are primerless, self-bonding grades that adhere to various plastic substrates (e.g. PA, PBT) and metals. The bonding is improved by a subsequent heat treatment process (e.g. one hour at 100°C) or by a longer storing at room temperature. The cured rubbers show a lower coefficient of friction without exuding oil as happens in oilbleeding silicone elastomers.
