Matting Hardener M68
KC1068 is the salts of polycarboxylic acid with cyclic amidine. The
hardener, applied in suitable formulations can produce epoxy or
Hybrid coatings for matt or semi-matt gloss with very good flow and
properties. Variation between matt and semi-matt surface can be
obtained by means of suitable adjustment of formulation
★Appearance: White powder
★Melting point: 210-230°C
★Non-volatile: Min. 98.5%
★The hardener may be applied both in pure epoxy and hybrid
(epoxy-polyester) resin powder coatings.
★Epoxy coatings of gloss range level ranging from 5% to10% and
hybrid coatings with gloss levels ranging from 10% to 70% may
easily be formulated by the use of KC1068.
★Powder coating produced with KC1068 is characterized by color and
gloss stability under normal baking conditions.
★Hybrid coating with matt or semi-matt gloss may be achieved by
replacing some of the polyester in the formulation with an
equivalent quantity of KC1068.
