Multifunctional acrylates have found utility as effective anti-reversion agents in sulfur cured applications where overcure or high temperature cure conditions exist. In this paper, a new multifunctional acrylate product is evaluated in both conventional and semiefficient vulcanization systems. Reversion resistance and cured physical properties of the resulting natural rubber/carbon black vulcanizates are compared to other commercial products and efficient vulcanization systems.
