Product Description: BENOX? L-40LV is a low viscosity, sprayable dibenzoyl peroxide dispersion. Designed primarily for "curing" unsaturated polyester and vinyl ester resins, it offers a number of advantages: Low water content Faster gel-to-peak time than MEKP systems Lower exothermic effects than MEKP systems Less "packaging" in spray equipment used to apply dibenzoyl peroxide dispersions More stable and less separation than common BPO dispersions on the market Less viscosity fluctuation BENOX? L-40LV can also be used as a sprayable dispersion for vinyl monomers (e.g. styrene, styrene, etc.). 40LV can also be used as an initiator for the polymerization of ethylene monomers (e.g. styrene, acrylates, etc.). Technical Data: Diphenyl
