Abstract
The present invention relates to a two-component coating composition comprising (1) a paint base component comprising (A) at least one polycarbonate diol, (B) at least one diamine having secondary amino groups and having an aliphatic group (b1) between the nitrogen atoms of the amino groups, and also (2) a hardener component comprising (C) at least one polyisocyanate-modified polyester having an isocyanate content of 4% to 15%. The present invention also relates to a method for coating substrates by applying the coating composition, and to the use thereof.
Claims17
A two-component coating composition, comprising:
- (1) a paint base component, comprising:
- (A) at least one aliphatic and linear polycarbonate diol having an OH number of 100 to 500 mg KOH/g,
- (B) at least one diamine comprising secondary amino groups and having an aliphatic group (b1) between the nitrogen atoms of the amino groups, and
- (2) a hardener component, comprising:
- (C) at least one polyisocyanate-modified polyester having an isocyanate content of 4% to 15%,
- wherein the two-component coating composition does not comprise a wax, a wax-like compound, or both.
