Polycarboxylic Acid, Brand Name : deping

We are offering polycarboxylic acid.
curing agent mb68/matt hardener mb68 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.

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%~10% and hybrid coatings with gloss levels ranging from 10%~70% ( or greater ) may easily be formulated by the use of mb68. Coatings produced with mb68 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 mb68.
