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.
Accelerator™ 383SN is a solution of 4% metal complexes for curing unsaturated polyester resins in combination with organic peroxide at room and elevated temperatures.
