    Product Mark: XYlink311
    Chemical Name: 4,4’-complex of diaminodiphenylmethane (MDA)and sodium chloride
    [Use and Performance]
    XYlink311 is equivalent to foreign Caytue®31 DA, which is mainly used for TDI (toluene diisocyanate) / polyester or polyether, amine curing agent of delayed reaction of MDI (diphenyl methane diisocyanate) / polyester or polyether urethane pre-polymer. It is composed of complex of symmetric aromatic diamine and sodium chloride, and dispersed in ester plasticizer, in which the content of free amine is very low. At room temperature, it is almost no activity, but heated to 120℃ (addition of catalyst can be reduced to 70-80℃), this salt complex begins releasing and the free diamine quickly reacts with pre-poly to form elastomer. Because XYlink311 is a liquid with appropriate viscosity, without melting, under room temperature it can be mixed with pre-polymer, suitable for normal pressure casting, pressure or injection molding, rotary casting and leaching in reaction kettle and other molding processing technology. It is especially suitable for large area construction, precision casting, microwave curing and other processing forms without requiring kettle life and stability limits. With curability similar to MOCA, there won’t appear gel phenomenon when mixed with pre-polymer without being heated, may be used as pre polymer of MDI system. XYlink311 can be ideally used for manual operation of processing liquid polyurethane elastomer and automatic mixing pouring equipment.
    This product is packed with galvanized iron drum, 20kg per drum.
    Store with room temperature, avoid light and in dry and ventilated place to avoid damp. If only part of the raw material is used in the container, the remaining should be carefully sealed.
