- Application Details
- ELASTOSIL® R plus 4285/30 may not be cured with peroxides, but only with the catalyst batch ELASTOSIL® AUX Batch PT 1. ELASTOSIL® R plus 4285/30 and ELASTOSIL® AUX Batch PT 1 are homogenously mixed in a ratio of 100:1.5 on a roll mill.
- Care must be taken to keep the compound cool during mixing. Temperature should not exceed 35°C temperatures reduce the pot life significantly.
- Crosslinking begins when ELASTOSIL® AUX Batch PT 1 has been added. The rate and degree of crosslinking depend on the storage time and temperature. At 23°C the mixture has a pot life of about 24h. This can be extended by storing the catalyzed mixture at a lower temperature.
