Metox-BW80 can be used for curing unsaturated polyester resins (UPR), gelcoats and vinyl ester resins based on bisphenol A and novolak resins, in the presence of a cobalt accelerator
or in the cobalt / amine system. The use of the second accelerator system shortens the gelation and curing times. In the case of the standard ortho-aluminum resin, it shows a longer gelation time than the standard one Metox-50W initiator. Recommended for production where long gelling times are required and in the summer when using standard MEKP results in obtaining too short gelation times. Use of standard MEKP-based initiators for UPR curing causes foaming. The peroxide is responsible for this effect hydrogen. In Metox-BW80, its content was reduced, which resulted in a significant reduction in foaming.
