摘要:
The present invention relates to a process for applying a topcoat to at least one side of a substrate, comprising a step (a) of at least partly coating at least one substrate metal surface, at least partly coated with at least one primer coat, with an aqueous coating composition which comprises at least one polymer dissolved or dispersed therein, the coating composition further comprising at least one mixed hydroxide of the general formula (I), and the process being a coil coating process; to a topcoat applied to at least one side of the substrate and obtainable by this process; to a substrate at least partly coated on at least one side with a topcoat by this process; and also to a use of this coating composition for at least partly coating at least one substrate metal surface, at least partly coated with at least one primer coat, with a topcoat in a coil coating process.
摘要:
The present invention relates to a method for manufacturing coated can lids from aluminum strip, and is based on the finding that flexible, easily formable coatings having high abrasion resistance result from the use of water-based lacquers containing a copolymer or a copolymer mixture of at least one aliphatic, acyclic alkene with at least one α,β-unsaturated carboxylic acid in water-dispersed form, and a curing system. In a preferred embodiment of the method, the application of a primer coating can be dispensed with entirely when water-soluble compounds of the elements Zr and/or Ti in the lacquer are used as the curing system.

摘要:
A process for the production of a multi-layer coating includes applying a coating layer from an aqueous pigmented coating composition A onto a substrate provided with an EDC primer and applying a base coat layer from an aqueous coating composition B overlying the coating layer. A clear coat layer is applied onto the base coat layer and the three coating layers are jointly bake-cured. The coating compositions A and B are different from each other and coating composition A comprises (i) binder solids, (ii) free polyisocyanate, (iii) a pigment content free of special effect pigments and comprising carbon black pigment and/or titanium dioxide pigment, and (iv) talcum filler.
