Patent Summary
A powder mixture comprises 20-80 wt% of one or more powdered organic peroxides, specifically dibenzoyl peroxide or substituted dibenzoyl peroxides (preferably di(4-methylbenzoyl) or di(2-methylbenzoyl) peroxide), 20-80 wt% of a powdered filler material, and 0-20 wt% water. At least 60 wt% of the filler material consists of a solid inorganic flame retardant, such as aluminium trihydroxide (ATH), magnesium dihydroxide (MDH), hydrotalcite, organically modified hydrotalcite, or combinations thereof, including hydrated forms. The mixture serves as a safer, low-water alternative to BaSO4-based compositions for use as a curing agent in coating compositions, unsaturated polyester, vinyl ester, and (meth)acrylate resin systems, or as an initiator in radical polymerization processes.
