Notice
MATT HARDENER compatibility with resin isn’t well for its high melting point, to avoid this default it’s necessary to distribute them or to make the curing temperature at a higher level. In case of epoxypolyester hybrid powder coatings, the polyester should be low acidity. Before achieving the ideal gloss and multiple characteristics tests are needed.
