Chlorendic anhydride is a chlorinated bicyclic anhydride used primarily as a curing agent and modifier in high-performance epoxy resins. It enhances thermal stability, flame resistance, and chemical inertness in cured systems. The compound is valued for its rigid molecular structure, which improves the mechanical properties of polymers under elevated temperatures.
The material is typically supplied as a white to pale yellow crystalline powder with a purity of 98% or higher. It contains trace levels of residual chlorine and may include minor isomers such as endo-chlorendic anhydride. Standard industrial grades are free from heavy metals and halogenated solvents. The compound is hygroscopic and requires dry storage under nitrogen or desiccated conditions.
End-users include manufacturers of aerospace composites, electrical insulators, and flame-retardant coatings. The product is packaged in 25kg multi-wall paper bags with inner polyethylene lining or 500kg bulk bags. Trade terms are usually FOB Cape Town or CIF, with minimum order quantities starting at 500kg. Lead time is approximately 20 to 30 days after order confirmation.

Before ordering, confirm the CAS number (115-28-6) and request a Certificate of Analysis showing acid value, chlorine content, and impurity profile by GC-MS. Verify that the product is free from residual hexachlorocyclopentadiene and solvents. Ensure packaging is moisture-proof and labeled with batch number, expiry, and hazard symbols per GHS standards.
Confirm the Incoterms - FOB Cape Town is standard, but CIF may be arranged. Lead time is typically 20 to 30 days after payment, but customs clearance in destination countries may add delays. Payment is usually via T/T in advance or LC at sight. Request shipping documents including bill of lading, MSDS, and export declaration to comply with your country’s chemical import regulations.
Upon receipt, inspect for clumping, discoloration, or odor - signs of moisture exposure. Conduct a small-scale cure test with your epoxy resin to verify reactivity and final Tg. Retain a sample for independent lab testing of chlorine content and impurity levels. Ensure all documentation meets your local chemical safety and environmental compliance requirements.
