Metox-BW90 can be used to cure unsaturated polyester resins (UPR), gelcoats and vinylester resins based on bisphenol A and novolak, in the presence of a cobalt accelerator or in the cobalt / amine system. The use of a second accelerator system shortens gelation and curing times. In the case of a standard ortho-aluminum resin, it has a longer gelation time compared to the standard Metox-50W initiator. Recommended for production where long times are required gelation and in the summer, when the use of standard MEKP causes too short times
gelation. Compared to Metox-BW85, it has a shorter gelation time. Use of standard MEKP-based initiators for UPR curing causes foaming. The peroxide is responsible for this effect hydrogen. In Metox-BW90, its content was reduced, which resulted in a significant reduction in foaming.
