3M™ Dynamar™ Rubber Curative RC 5251Q

• Functions as an acid receptor for ECO compounds
• Used as part of a cure system for vulcanizing polyepichlorohydrin elastomers
• Delivered in powder form

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. In non-lead containing polyepichlorohydrin compounds, RC 5251Q functions as the acid acceptor.
