Polyisocyanate curing agent

    AK-17150 is a closed polyisocyanate curing agent for powder coatings, designed to cure with hydroxy polyester 
    or hydroxy acrylic resin to provide a smooth, weather-resistant and highly cross-linked powder coating. 

    1.Typical properties 
    Appearance              white to pale yellow granule        [visual] 
    NCO content (%)     14-16                                            [Di-n-butylamine method] 
    Free NCO(%)           1.0                                           [Di-n-butylamine method] 
    Tg(℃)                 45-55                                           DSC 
    Herein described to be typical properties and do not constitute specification limits.

    2.Characteristics 
     Extremely high crosslink density , excellent surface hardness and chemical resistance for coating . 
     Excellent leveling and smoothness. 
     Excellent weather resistance.


    3.Use method & levels 
    Equivalent weight of this product is approx 275. It is recommended to cure with hydroxyl polymer in equivalent 
    amount (13:87 for polyester with hydroxyl value of 30; 20:80 for polyester with hydroxyl value of 50). Tin-based 
    catalysts can significantly improve coating mechanical properties and solvent resistance. 
    Unsealing temperature of this product is above 170, so it is recommended to fully cure at 180*20min or 200℃ 
    @15min

    4.Package & Storage 
     Packaging with PE lined Kraft paper bags. Net weight 25kg per bag. 
     Store in temperature under 32℃ and cool dry place to avoid caking. Keep package closed after using. Keep 
    away from heat and fire. 
     based on our experience the shelf life of this product under above conditions is
