- Application Details
ELASTOSIL® LR 3842/40 A/B is particularly suitable for the economical production of weather packs in the automotive industry. They are increasingly being used to produce cable and connector seals. As an oil film forms, seals can be fitted easily and fully-automatically, even when tolerances are narrow.
Processing
The A and B components are delivered ready to use in 20 kg pail and 200 kg drum kits. 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.
