Peroxide catalysts

Peroxide catalysts

In the field of thermosetting resins with monomer (unsaturated polyester, vinyl ester and urethane-acrylate resins) the peroxide is a substance added to resins or gel coats in controlled quantities to cause gelation and crosslinking. The catalyst reacts with the accelerator, thereby creating free radicals that, in turn, initiate polymerization. 

The most comon of all is the MEKP (methyl ethyl ketone peroxide), although there are many others:dibenzoyl peroxide, cumyl,acetyl acetone, cyclohexanone, etc.
