Application:
Epoxy matting Hardener YS68 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 flowing and properties. Variation between matt and semi-matt surface can be obtained by means of suitable adjustment of formulation.
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 YS68.The following gives the formulations of hardeners for matt epoxy coatings.

D68 is a leveling agent with silica carrier available from. It's noted that the achievement of matt effect and relevant puppetries of the film is connected with full cured of coatings. Thus, the following cure schedules are recommended.
