Primid/Curing agent SA3120A

High purity-hydroxyalkylamide crosslinking agent. It is a substitute of TGIC. Has proven weather-resistance and low temperature curing (150℃) property. Exhibits enhanced charging properties so better powder transfer efficiency could be obtained. Possesses flow and mechanical properties. Compared with basic SA3120, it improved characteristics of anti-hydrolysis aging and anti-yellowing when over burning. Used in powder coatings. Recommend to design formulation by weight parts of 95/5 [resin to SA3120A] for polyester resin with AV ca.34mg KOH/g; 96.5/3.5 for polyester resin with AV ca.22mg KOH/g.
