3M™ Dynamar™ Elastomer Additives FC 5157E, FX 5166 and RC 5251Q are designed as a curative package to be added to ECO, NBR or NBR/PVC to enhance bonding of these materials to bisphenol-cured FKMs without the need for external bonding agents.
This package, when added to non-lead containing ECO compounds, allows the processors to eliminate lead from their formulations, yet maintain excellent heat-age properties. FC 5157E functions as the vulcanizing agent.
