Data sheets
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.
Storage
The "Best use before end date" of each batch is shown on the Certificate of Analysis. Storage beyond the date specified on the Certificate of Analysis does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
