The curing agent HAA (HH8081) is a tetra-functional group containing N,N,N’,N’-Tetrakis (β-hydroxyethy) adipamide (HAA). It is suitable for curing with carboxyl-terminated polyester or acrylic resin to produce exterior durable powder coatings with excellent mechanical properties and good weather durability. In comparison with TGIC, it’s non-toxic, and can be used to produce non skin irritant and safe outdoor powder coating.
