Technical Data Sheet
M44
Crosslinker for exterior durable polyester powder coatings
Description
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.
