    Velsicol CHLORENDIC ANHYDRIDE is a solid, reactive flame retardant. An acid anhydride with a chlorine content of 54.5%, it imparts permanent flame retardance, high heat distortion, and excellent corrosion and abrasion resistance to resins such as unsaturated polyesters and alkyds. Chlorendic Anhydride is also used as a cross-linking agent in epoxy resins as a low-smoke component in polyols for rigid polyurethane foams and in UV curable inks and coatings for its adhesion to metal. Resin systems containing Chlorendic Anhydride can be formulated to meet ASTM E84 (Underwriter’s Tunnel Test) UL-94 and ASTM E 162-78 (Surface Flammability Test) as well as to meet U.S. military specifications for flame retardant, corrosion- resistant coatings.Unsaturated polyesters resins made from Chlorendic Anhydride are used in flame-retardant, glass- reinforced polyester composites for boats, construction panels, electrical applications and machine housings. In polyester corrosion-resistant applications, Chlorendic Anhydride is used in piping and in tanks and scrubbers for the chemical, fertilizer and pulp industries.Epoxy resins from Chlorendic Anhydride can be used as laminates for electrical uses, potting and encapsulation, adhesives requiring flame resistance, and high-heat distortion and protective coatings where permanent flame retardance, heat resistance, corrosion resistance and abrasion resistance are required.Alkyd coatings from Chlorendic Anhydride-based alkyds are used extensively for industrial and marine coatings applications. They are used in approved coating formulas, meeting military specifications Mil-R- 21417 for Navy ships and in industrial environments requiring chemical resistance combined with flame retardance.UV curable ink and coatings from Chlorendic Anhydride are used in polyester-based coatings and inks to provide good adhesion to metal, fast curing and hardness. In heat-fusible polyester and alkyd inks, it provides good adhesion to plastics, flexibility and high gloss.
