Luperox ANS55 Dibenzoyl peroxide (94-36-0) Arkema North America South and Central America Western Europe Central and Eastern Europe Middle East and Central Asia Asia / Pacific Crosslinking / Coupling / Curing Agents Acrylic/Acrylate Resins Polyester >> Unsaturated Vinyl Coatings Architectural / Decorative Automotive OEM General Industrial /Maintenance Soluble in Methyl Ethyl Ketone Insoluble in water Soluble in benzene Soluble in acetone Diacyl peroxides are free-radical initiators which can be decomposed to useful free-radicals when heated or when activated by various promoters. They are widely used as initiators for vinyl monomer polymerizations, as curing agents for unsaturated polyester resins, as crosslinking agents for elastomers and diacyl peroxides are used for bleaching flour. Diacyl peroxides are used in a broad spectrum of applications including curing of unsaturated polyester resins, crosslinking of elastomers and production of PVC, Polystyrene and Polyacrylates. Benzoyl peroxide can be promoted to achieve room temperature polymerization of unsaturated polyester resins and acrylic monomers. Tertiary amines such as dimethyl aniline are normally employed as promoters. (Luperox A75) and Succinic Acid Peroxide are shock-sensitive. Commercial diacyl peroxides (except Luperox A98) are formulated to eliminate this hazard. 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.
