Luperox 500R Dicumyl Peroxide 80-43-3 Arkema North America South and Central America Crosslinking / Coupling / Curing Agents Acrylic/Acrylate Resins Polyester >> Unsaturated Vinyl Coatings Architectural / Decorative Automotive OEM General Industrial /Maintenance Methane Luperox® 500R is Dialkyl peroxides,the free radicals generated from dialkyl peroxide decomposition are efficient for crosslinking and modification of polyolefins (polyethylene, ethylene-vinyl acetate and polypropylene); vulcanizing agents for elastomers (ethylene propylene copolymers and terpolymers); curing agents for polyester resins; initiators in bulk, and suspension vinyl polymerizations and as synergists for flame retardant polymers. The most common monofunctional di-tertiary alkyl peroxide is dicumyl peroxide. When subjected to heat, dialkyl peroxides decompose homolytically (first order) into two free radicals.The products obtained from the thermolytic decomposition of dialkyl peroxides depend upon the nature of the peroxide and the decomposition environment. Free-radical initiators. Used in the production of acrylic resins for paint and coatings. Offers low molecular weights and narrow polydispersities, high quality, colorless, results.
