    Uses:(1) It is an outstanding chain extender for high performance elastomeric polyurethanes and also 

    curing agent for epoxides (EP). It provides improved mechanical and dynamic properties which cannot 

    be achieved with standard formulations. It is preferably used with low TDI free polyurethane pre-polymers. 

    It provides excellent mechanical properties with low heat build-up under regular high compression loads, 

    superior hydrolytic resistance up to temperatures of 150°C (300°F), low wear and tear, and can be processed 

    easily with ribbon-flow technology PU formulations based on it are suitable for cast elastomers, RIM elastomers 

    and coatings including spray coatings. In EP it is suitable for tooling, prepregs and chemical resistant coatings. 

    Compared to the conventional MOCA curative, it provides exceptional dynamic performance, improved high 

    temperature capability and expanded elastomer service temperature range. (2) It may be used as a precursor 

    for polyimides and as an intermediate for organic synthesis.


    Packing: in 25kgs net drum
