  • ProductApplications

    Accelerator™ 553SN is a solution of metal complexes, partly based on a cobalt salt in an organic solvent. Accelerator™ 553SN gives in comparison with the commonly used cobalt accelerator a much faster cure with comparable gel time. Accelerator™ 553SN is therefore very suitable where a faster demoulding time of the end product is required. Application areas are for instance: Gelcoat, RTM, production of polymer concrete. Accelerator™ 553SN can successfully be used for the production of cobalt pre-accelerated UP resins. The use of Accelerator™ 553SN will strongly reduce the gel time drift as observed with standard cobalt. Accelerator™ 553SN prevents foaming in VE resins with standard MEKP e.g. Butanox M-50.
