Assignee:

BASF Aktiengesellschaft - Ludwigschafen

International Classification:

B05D 702

US Classification:

4273935

Abstract:

The present invention relates to a method of coating substrates, especially those with a hydrophobic surface, in which the substrate to be coated is coated with a coating composition whose binder is a formulation comprising an aqueous polymer dispersion in which the polymer has carbonyl or oxirane groups (component a)), and at least one compound having at least two NH. sub. 2 groups per molecule, is applied to the substrate to be coated �sic!. It also relates to coating compositions including such binder formulations, and furthermore to a method of sealing using a sealing composition including such formulations as its binder.

Assignee:

BASF Aktiengesellschaft - Ludwigshafen

International Classification:

C08K 524

US Classification:

524190

Abstract:

The present invention relates to the use of compositions comprising at least one aqueous polymer dispersion wherein the polymer has carbonyl or oxirane groups (component a)) and at least one compound with at least two NH. sub. 2 groups per molecule as sealing or coating compositions, especially for substrates with a hydrophobic surface. The present invention further relates to coating compositions containing such binder formulations.
