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.
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.
