Application
Based on aminoplast -hydroxyl polyester chemistry, AHA1209 is specially designed as attractive crosslinker for exterior durable powder coatings to provide outstanding weather resistance, high light /color stability, high surface hardness and excellent mechanical property as well as consistent structure effect, esp. wrinkle and alligator finishes.
Catalysts
Depending on different types of catalysts AHA1209 may achieve different appearance varying from glossy and matt to texture finishes. In general, amine- blocked sulfonic acid
catalysts will provide desirable wrinkle or alligator finishes whereas “nitrogen acid” such as sulfoimide compound to be flat glossy. All of these catalysts, if desired, will be available along with AHA1209 by AHA.
Use levels
Mix ratio approx. 94/6 of OH value 30-40 mg KOH/g polyester to AHA1209.
