m-xylylenediamine

m-Xylylenediamine (CAS 1477-55-0), commercially known as MXDA, is an aromatic diamine used as a reactive building block in polymer synthesis and curing systems. Its two primary amine groups enable it to form durable, high-performance polymer networks. MXDA is a key monomer in the production of polyamide MXD6, a high-barrier resin used in food packaging films and multilayer bottles where oxygen transmission must be minimized. This makes it essential for modern packaging solutions.

In epoxy systems, it functions as a room-temperature curing agent, producing coatings and adhesives with strong chemical resistance. These are ideal for industrial flooring, pipelines, and protective linings in harsh environments. The compound also serves as a chain extender and crosslinker in polyurethane and isocyanate-based formulations. These applications target structural adhesives and composite materials requiring high mechanical strength.

In specialty gas barrier packaging, MXDA-based polymers are compounded into blends that extend shelf life. This is particularly important for oxygen-sensitive food and beverage products in the global supply chain. m-Xylylenediamine is supplied as a clear to pale yellow liquid in standard commercial and technical grades. Packaging options typically include drums and IBC containers suited to bulk industrial procurement needs.

Material is available to specifications aligned with polymer-grade and epoxy-grade purity requirements. This ensures consistent performance depending on the specific end application and industrial manufacturing standards.
