Compounds that are stable at room temperature and unstable at higher temperatures and are easily decomposed to produce an active (unstable) free radical are capable of initiating the polymerization of unsaturated monomers and resins. Organic peroxide compounds and hydroperoxides are widely used as initiators of free radical polymerization reactions in various industries, including the synthesis of polymeric resins and emulsions for plastics, coatings, rubbers, adhesives, etc. These compounds are based on film-based two-component coatings. Polymerization of unsaturated resins or their copolymerization with monomers are used. In this group, the most common applications are for unsaturated polyester base coatings and acrylic resins.
Application
Di-tertiary-butylperoxide, Di (2-ethylhexyl) peroxydicarbonate, Tert-butyl peroxy benzoate, Lauryl Peroxide, etc. are used for baking unsaturated polyester resins, polystyrene, polyvinyl acetate, linear polyethylene, etc.
