Promoters - Accelerators
Accelerators are compounds used in the polyester and vinyl ester resins to speed up the curing reaction. Most of the Poliya’s resins and gelcoats are pre-promoted. Depending on conditions, promoters can be added by the composite manufacturer prior to adding catalyst to the resin. In general cobalt-based promoter helps the catalyst to start the chemical reaction between the resin and styrene monomer and form a cured solid.
