Abstract:
The invention relates to a method for producing a multi-layer coating structure, comprising the following steps: a) providing a substrate; b) applying at least one base-coat layer, wherein the base-coat layer is substantially free of melamine and derivatives thereof; c) applying at least one clear-coat and/or top-coat layer, comprising at least one polyisocyanate, at least one NCO-reactive compound, and at least one thermally latent catalyst; d) waiting for at least 30 s after step c) such that a film can form; e) curing the multi-layer coating structure while supplying heat. The invention further relates to the multi-layer coating structure that can be obtained from the method according to the invention, to the use of the multi-layer coating structure to coat substrates, and to substrates coated with the multi-layer coating structure.

Claim (Index 8):
