Matting Hardener for Powder Coating

SA68 is the salts of poly carboxylic acid with cyclic amidine which can be used in epoxy or Hybrid coatings for matt or semi-matt gloss with very good flowing and properties. It can be applied both in pure epoxy and hybrid (epoxy-polyester) powder coatings. Gloss ranges from 5~10% in Epoxy coatings and 10~70% in Hybrid coatings. Variation between matt and semi-matt surface can be obtained by means of suitable adjustment of formulation.
