Application Details

These grades are particularly suitable for the economical production of large series of injection-molded articles. Parts made from ELASTOSIL® LR 3003/03 A/B can be used for technical applications.

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.
