Coagent monomers.

Saret SR517R trimethacrylate and SR519R triacrylate coagent monomers incorporate a proprietary retarder technology for improved scorch safety in high temperature mixing and curing processes. Said to be ideal for rubber applications, these coagents demonstrate outstanding performance in automotive belts, hoses, seals and gaskets, and in wire and cable, according to the company. SR517R and SR519R are designed for use with elastomers that require higher processing temperatures or extended mix cycles. The chemistry is said to improve temperature stability, allowing the monomers to be used in higher temperature processes, yet maintain ultimate scorch safety. The proprietary scorch retarders are less volatile, and thus remain in the rubber compound through mixing and forming so they are available when required during curing. (Sartomer)
