    Accelerator 553SN
  • Chemical family

    Metal accelerator
  • CAS number

    136-52-7
  • Physical form

    Liquid
  • Regional availability

    Africa, Europe, India, Middle East
  • Chemical name

    Cobalt(II) 2-ethylhexanoate in solvent mixture
  • Applications

    Accelerator 553SN is a solution of metal complexes, partly based on acobalt salt in an organic solvent. Accelerator 553SN gives in comparison with the commonly used cobalt accelerator a much faster cure with comparable gel time.

Market Segments

Thermoset composites

Detailed description

Accelerator 553SN is a 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.
