What is 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.
Where is m-xylylenediamine used?
- Polyamide MXD6: key monomer for high-barrier resin in food packaging films and multilayer bottles where oxygen transmission must be minimized
- Epoxy systems: room-temperature curing agent for coatings and adhesives with strong chemical resistance
- Polyurethane and isocyanate-based formulations: chain extender and crosslinker
- In specialty gas barrier packaging, MXDA-based polymers are compounded into blends that extend shelf life.
Commercial specifications
- Packaging: drums and IBC containers
- Polymer-grade and epoxy-grade purity requirements
