Solution of 1.9% metal complexes for curing unsaturated polyester resins in combination with organic peroxide at room and elevated temperatures. Typically recommended for pre-acceleration of vinylester resins to avoid foaming during cure when using standard MEKP. Applications: Accelerator 553S is a solution of metal complexes, partly based on a cobalt salt in an organic solvent. Accelerator 553S gives in comparison with the commonly used cobalt accelerator a much faster cure with comparable gel time.
