Cobalt Accelerator

The curing of unsaturated polyester resins at ambient temperatures can in general not be performed by an organic peroxide alone. The radical formation, which is necessary to start the polymerization reaction, is at ambient temperatures with most generally applied organic peroxides too slow. To speed up the radical formation in a controllable way organic peroxides must therefore be used in combination with an accelerator. All our standard resins are supplied pre-accelerated, but to achieve quicker setting times more accelerator can be added.
