WC-540 Polyurethane Elastomer will achieve the best results when vacuum degassed. Faster systems such as these do not have the time to release air bubbles sufficiently. Vacuum degassers help remove air from the mixed material prior to pouring into your mould. For the best results, please familiarize yourself with the post-curing schedule outlined in the TDS.
