Powder clear lacquer or slurry used for making clear lacquer, e.g. for car on aqueous base coat, contains polyol in addition to epoxide, tris(alkoxycarbonylamino)triazine and polycarboxylic acid

摘要

Polyol(s) (I) is/are used in powder clear lacquers and slurries containing (a-1) epoxide binder(s) and (b-1) tris(alkoxycarbonylamino)triazine(s) (II) and polycarboxylic acid(s) and/or a carboxy-functional polyester as hardener or (a-2) (II) and oligomeric or polymeric epoxide hardener(s) and/or low-molecular epoxide hardener and (b-2) polymeric binder(s) containing carboxyl group. Polyol(s) (I) is used in powder clear lacquers and slurries containing (a-1) epoxide binder(s) with 0.5-40 wt.% polymerized glycidyl monomer and (b-1) tris(alkoxycarbonylamino)triazine(s) (II) and polycarboxylic acid(s), especially linear dicarboxylic acid, and/or a carboxy-functional polyester as hardener or (a-2) (II) and oligomeric or polymeric epoxide hardener(s) containing 0.5-40 wt.% glycidyl monomer and/or low-molecular epoxide hardener and (b-2) polymeric binder(s) containing carboxyl group. An Independent claim is also included for clear lacquers produced from these lacquers or slurries.
