Methyl ethyl ketone peroxide (MEKP) in diisononyl phthalate.
Butanox LPT-IN is a special initiator designed for curing unsaturated polyester resins in the presence of a cobalt accelerator at room or elevated temperature.
Compared to most ketone peroxides, Butanox LPT-IN provides a much longer gelling time.
Therefore, it is ideal for applications where a longer production time is required (e.g. for the production of large components or in winding technology).
