Accelerator 383 is a solution of metal complex, partly based on a cobalt salt in an organic solvent, developed for the curing of unsaturated polyester resins in combination with an organic peroxide at room and elevated temperatures.
Accelerator 383 gives in comparison with the commonly used cabalt accelerator Accelerator NL-51P(=6% cobalt) a much faster cure at a comparable gel time.
Accelerator 383 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 can not be accepted.
Application area are for instance: standard hand lay up and spray up applicatiopns, resin transfer molding, the production of polymer concrete.
Accelerator 383 can successfully be used for the production of cobalt pre-accelerated unsaturated polyester resins.
The use of Accelerator 383 will strongly reduce the gel time drift as observed with standard cobalt carboxylates. |
