Product use
Amine catalysts 33 lv mainly used for polyurethane foam gel catalyst, widely used in the soft, semi-hard, rigid polyurethane foam plastics, coatings, elastomers, in polyurethane foam system, isocyanate and first three ethylene diamine complex reaction activity, the nature of the complex is very unstable, once the carbamate key generation, it will be free to come out, is conducive to further catalytic, triethylene diamine on the gel and foam reaction has a strong catalytic effect, especially for the catalyst selectivity of polyurethane and hydroxyl.
