- Application Details
Selfbonding ELASTOSIL® LR 3675 grades adhere to various plastic substrates (e. g. PA, PBT) and metals, but not to the mold. Because of the individual surface properties adhesion to the substrate must be tested before production. ELASTOSIL ® LR 3675 can generally be used for technical applications without post-curing, e.g. connector seals in the automotive industry.
Processing
The A and B components are delivered ready to use in 20 and 200 liter drums. With adequate metering equipment, they can be pumped directly from the original containers into the injection molding machine and mixed by a static mixer. The mixing ratio is 1 : 1. At room temperature, mixtures of A and B components have a pot life of at least three days. Start-up of new molds should be supported by use of ELASTOSIL® AUX Mold Release Agent 32.

- 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.
- Note
Cure conditions : 5 min / 165°C in press.
