High purity β-HAA Hardener for polyester powder coatings

K3120A is a high purity ß-hydroxyalkylamide crosslinking agent,it is a substitute of TGIC. Curing with carboxyl-terminated polyester or acrylic resin to make weather resistance powder coatings.

1.Typical properties

Herein described to be typical properties and do not constitute specification limits.

2.Characteristics

1. Non-toxic compared with TGIC, the resulting TGIC-free based exterior durable powder coatings are non-toxic, non-irritant to skin and safety to human body.
2. Proven weather-resistance and low temperature curing (150℃) property.
3. Exhibited enhanced charging properties so better powder transfer efficiency could be obtained.
4. Excellent flow and mechanical properties.
5. Compared with basic K3120,it improved characteristics of anti-Hydrolysis aging and anti-yellowing when over burning.
