Liquid Coagent optimizes properties of rubber and plastic.September 17, 2012 -
Encompassing both Type I and Type II classifications, SR523 Coagent minimizes cure times and optimizes processability of peroxide-cured elastomers compared to conventional coagents such as triallyl cyanurate. Product demonstrates scorch resistance and remains clear at ambient temperature. Coagent is suitable for rubber and plastics used for building profiles, injection molded goods, radiator hoses, wire and cable insulation as well as O-rings, gaskets, and seals.

EXTON, Pa., – Global specialty chemicals manufacturer Sartomer USA, LLC now offers SR523, a liquid coagent that shortens cure times and improves processability of peroxide-cured elastomers compared to conventional coagents like triallyl cyanurate (TAC). SR523 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.
It is an advanced coagent that has a unique structure encompassing both Type I and Type II classifications. This coagent exhibits an improved rate and state of cure in elastomer compounds. In addition, SR523 aids in the treatment of such compounds by reducing mixing torque and improving processability.
Other elastomeric properties were also shown to increase with SR523, including the tensile modulus. Higher concentrations of this coagent during testing resulted in slightly greater increases to a compound’s modulus compared to other coagents, including trimethylolpropane triacrylate (TMPTA) and triallyl cyanurate (TAC). In fact, SR523 provides a significant advantage over TAC because it remains a clear liquid at ambient temperature while TAC solidifies. The SR523 coagent also demonstrates a high scorch resistance.
Formulators interested in learning more about SR523 can inquire with Sartomer at this year’s International Rubber Expo from October 9th to 11th (booth #420). Technical documentation is also available for download at: www.sartomer.com/newsletter/SR523.
