Crosslinker for exterior durable polyester powder coatings
M43 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.
Appearance [visual] White granular solid
Melting point (℃) 100-115
Hydroxyl equivalent weight (g/eq.) 86-102
Volatiles (%) ≤0.5
