SR523 is a liquid coagent that can shorten cure times and improve processability of peroxide-cured elastomers compared to conventional coagents like triallyl cyanurate (TAC). The material reportedly improves the properties of rubber and plastics used for building profiles, injection molded goods, radiator hoses, wire, and cable insulation, as well as o-rings, gaskets, and sealants.

The advanced coagent reportedly has a unique structure encompassing both Type I and Type II classifications, and can exhibit an improved rate and state of cure in elastomer compounds.
