  • Applications

    Accelerator 383SN is a solution of metal complexes, partly based on a cobalt salt in an organic solvent, developed for the curing of unsaturated polyester resins in combination with organic peroxide at room and elevated temperatures. Accelerator 383SN gives in comparison with the commonly used cobalt Accelerator NL-51P (= 6% cobalt) a much faster cure at a comparable gel time. Accelerator 383SN is therefore very suitable for those processes where a faster demolding time of the end product is required but a shorter gel time or production time of the molding cannot be accepted. Application areas are for instance: standard hand lay-up and spray-up applications, resin transfer molding, the production of polymer concrete. Accelerator 383SN can successfully be used for the production of cobalt pre-accelerated unsaturated polyester resins. The use of Accelerator 383SN will strongly reduce the gel time drift as observed with standard cobalt carboxylates.
