ELASTOSIL® LR 3070/50 US A/B
- Chemical Family
- Silicones
ELASTOSIL® LR 3070/50 US A/B is a primerless, self-bonding liquid silicone rubber (LSR) grade that adheres to various plastic substrates, e.g. PA, PBT, and metals, but not to the mold surface. The bonding is improved by oven-curing for 1 hour at 100°C or 24 hours at room temperature.

- Properties
ELASTOSIL® LR 3070 series are primerless self-bonding grades that adhere to various plastic substrates e.g. PA, PBT and metals, but not to the mold surface. The bonding is improved by oven-cure for 1 hour at 100°C or 24 hours at room temperature. Because of individual surface properties, each substrate must be tested before production.
