Abstract
A process for the preparation of a coating layer comprising the steps: (a) applying a coating layer to a substrate from a coating agent of which the resin solids comprise a binder system curable by free-radical polymerization of olefinic double bonds, and containing 0.1 to 4 wt-%, based on resin solids, of a morpholin-2-one derivative sterically hindered by 3,3,5,5-polysubstitution as a light stabilizer; and (b) thermal curing of the applied coating layer.
Claims16
A process for coating a substrate with a thermally curable coating layer containing a hindered amine light stabilizer compound, the process comprising the steps of:
- (a) applying a coating layer comprising a coating agent to a substrate, wherein the coating agent comprises resin solids, wherein the resin solids comprise at least one binder system chemically cross-linkable by free-radical polymerization of olefinic double bonds, and wherein the coating agent further comprises 0.1 to 4 wt-%, based on resin solids, of a morpholin-2-one derivative sterically hindered by 3,3,5,5-polysubstitution;
- and
- (b) curing the coating layer of step (a) thermally.
