COATING COMPOSITION CURABLE BY THIO-MICHAEL ADDITION

摘要

The present invention relates to a curable coating composition comprising at least one Michael donor (A) having at least one thiol group, at least one Michael acceptor (B) and at least one specific catalyst (C), its use as a clear coating in a method to prepare a multilayer coating and a multilayer coating obtained from said process. Moreover, the present invention relates to a kit-of-parts comprising at least two separate containers C1 and C2, wherein the specific catalyst (C) is contained in container C1 and/or C2, preferably in container C1. Finally, the present invention relates to the use of specific salts of carboxylic acids as catalyst in a reaction between a Michael donor (A) having at least one thiol group and a Michael acceptor (B).
