Abstract:
A powder coating dispersion comprising a binder, a crosslinking agent, oxalic acid, and, optionally, a polyvalent inorganic acid, wherein at least one of:I) a) the binder comprises at least one epoxide-containing binder containing, based on the binder, from 0.5 to 40% by weight of at least one copolymerized glycidyl-containing monomer, and b) the crosslinking agent comprises at least one tris(alkoxycarbonylamino)triazine and at least one polycarboxylic acid; and/or II) a) the crosslinking agent comprises at least one tris(alkoxycarbonylamino) triazine and at least one epoxide-containing crosslinking agent containing, based on the crosslinking agent, from 0.5 to 40% by weight of at least one copolymerized glycidyl-containing monomer, wherein the epoxide-containing crosslinking agent is at least one of oligomeric and polymeric, and b) the binder comprises at least one carboxyl-containing polymer.
