Appearance: White powder
Melting point: 210-230°C
Non-volatile: Min. 98.5%
2.Application
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 M68.
Powder coating produced with M68 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 M68.
The following gives the formulations of M68 for matt epoxy coatings.
