Product Description
M-325 is a low-functionality hydroxyalkylamide. It is a hydroxyalkylamide curing agent aims at outdoor weather-resistant powder coatings. It can provide higher film thickness, and meanwhile has a better anti-yellowing performance than traditional HAA, especially suitable for high gloss powder coatings and applications requiring good outgassing properties.
Product Characteristics
1.Better flow performance and higher film thickness
2.Excellent weather resistance
3.Significant anti-pinhole performance
4.No hazard label required

Recommended Dosage
M-325 is suitable for curing with carboxyl polyester resins with an acid value of 20～80mg KOH/g. When the acid value of the carboxyl polyester resin is about 34mg KOH/g, the amount of M-325 added is 94.5/5.5 (by weight, carboxyl polyester resin/M-325).
