Catalyst
MEKP (Methyl ethyl ketone peroxide) initiates the Crosslinking of unsaturated polyester resins used in glass reinforced plastic, and casting it can be used at room and elevated temperature. Dibenzoyl peroxide can be used for the same purpose. (MEKP is generally better suited for resins, gels and flocoats, Dibenzoyl is generally more suited for polyester based bodyfillers, bridgers and gap pastes)
