| Accelerator 55028N is an cobalt accelerator in aliphatic solvent mixture for curing UP resins at ambient temperatures. Recommended when using Aluminum Trihydrate (ATH) fillers. Applications: 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 a so called accelerator. For ketone peroxides like methyl ethyl ketone peroxides, cyclohexanone peroxides and acetylacetone peroxide a cobalt accelerator must be used.
