Technical Data Sheet


Crosslinker for exterior durable polyester powder coatings



M44 is a novel β-hydroxyalkylamide crosslinker, which is especially designed to have 3 hydroxyl group functionalities, for formulating exterior durable carboxylic polyester powder coatings. Due to its chemical structure, M44 could provide long-gel time, better color stability and excellent over baking properties, therefore, a pinhole-free, high glossy powder coating with exceptional flow is easily formulated.
