  • Methyl propyl ketone peroxide formulations and their use in processes to cure unsaturated polyester resins
    Patent number: 6642287
    Abstract: Methyl propyl ketone peroxide formulations are claimed that can be safely handled at ambient temperature, are storage stable, and give fast curing rates of unsaturated polyester resins particularly when accelerated with a complex of two different metals. The claimed products are particularly suited for thin articles and coating such as suited for use in gel coat systems. The pure ketone peroxides consist of more than 60% by weight of type-4 methyl propyl ketone peroxide and used as formulations containing sufficient amount of a non-aqueous phlegmatizer.
