Description
BENOX L-40LV is a low viscosity, sprayable dispersion of dibenzoyl
peroxide.
BENOX L-40LV is specifically designed for use in curing
unsaturated polyester and vinyl ester resins and offers the following
advantages:
* Low water content
Faster gel to peak than MEKP systems
* Lower exotherm than MEKP systems
* Less packing in spray equipment designed/modified for
spraying dibenzoyl peroxide dispersions
* More stable and less separation than the common BPO
dispersions on the market
* Less viscosity drift
BENOX L-40LV may also be used as a polymerization initiator for vinyl
monomers, (e.g. styrene, acrylate, etc.).

Application
BENOX L-40LV is low viscosity dispersion and may separate slightly
on standing. It will remix easily and should be stirred immediately
prior to use. Continuous stirring during use in spray equipment will
