AHA6319 is an amine-blocked sulfonic acid salt based catalyst absorbed on silica used in exterior durable powder coating with wrinkle finishes. When combined with the special aminoplast crosslinkers, such as AHA 1209 or Powderlink 1174, the resulting powder coatings based on hydroxyl polyester resins will show the attractive wrinkle finishes.

AHA6552 is a tetra-functional group containing β-hydroxyalkylamide crosslinker. It, as a substitute of TGIC, is suitable for curing with carboxyl-terminated polyester or acrylic resin to provide TGIC-free based exterior durable powder coatings.

Wrinkle finish crosslinker for powder coatings. AHA 1209 is an aminoplast based crosslinker capable of providing durable wrinkle finishes used in powder coatings. Characteristics include - - Reaction with hydroxyl functional polyester resin resulting durable wrinkle finishes. - Special catalyst request to achieve different textured styles. - Structure patterns consistent and outdoor durable. - Excellent overbake resistance and anti-yellowing. - Low usage.

AHA6553 is an improved β-hydroxyalkylamide crosslinker for formulating exterior durable carboxylic polyester powder coatings. In comparison with normal HAA crosslinker this product could provide better anti-yellowing and higher color stability, therefore it is especially suitable to use in direct fired gas ovens.
