    XYlink M-CDEA is an aromatic chain extender. It has good compatibility with TDI-based prepolymer. The reaction of M-CDEA and prepolymer is faster than that of MOCA. XYlink M-CDEA is recommended mainly used for high-performance casting polyurethane elastomers, and can also be used in RIM PUs, microcellular polyurethane elastomers, and spray polyurethane-ureas, etc.
    Polyurethane elastomers based on this product have excellent physical properties such as hardness, tear resistance, heat resistance and dynamic mechanical properties (including dynamic heat-generation) than those based on MOCA. The PU elastomers have good cost effective when it mixed with chain extender MOCA and XYlink 740M. XYlink M-CDEA could also be applied as curing agent for epoxy resin and used to produce polyimides. XYlink M-CDEA has lower toxicity with Ames test negative and LD50 (rats) >5000mg/kg.

    2kg, 20 kg or 40kg net weight, packed inside with PP bag and outside with fiber drum or carton.

    This product should be stored in a well-ventilated and dry place. Keep it away from sunlight.
