1,Matt Hardener TP68 is a composed salt of cyclic-amidine and multi-acid. It utilizes the two different reaction rates of group in molecular structure, and during the curing process, it generates nonuniform shrinkage then forms the matt surface. It has both gloss decreasing and curing functionsMatt Hardener TP68 is a composed salt of cyclic-amidine and multi-acid.
2,Application MATT HARDENE TP68 is used for pure epoxy resin , epoxy\ polyester hybrid powder coatings to achieve coatings with matt surface having excellent mechanic quality and wonderful appearance.

4.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 epoxy\polyester hybrid powder coatings, the polyester should be low acidity. Before achieving the ideal gloss and multiple characteristics tests are needed.
5.Storage:The storage period could last a rather long time when it is kept inside the sealed container. Do seal the container again after taking some from it.shelf life is 3year without any problem.
