Abstract

The invention pertains to a method for providing a metallic or concrete surface of a chemical installation with a coating, which comprises the steps of: - providing a two-pack coating composition wherein the first pack comprises an epoxy resin and the second pack comprises an amine curing agent for the epoxy resin, the coating composition further comprising an organoboron compound of the formula (I), wherein X is an organic group having 1 to 24 carbon atoms and is linked to the boron atom via a carbon-boron bond, and wherein Y is an at least divalent organic group having 2 to 16 carbon atoms, combining the first pack and the second pack to form a coating composition, - applying the coating composition to the surface of a chemical installation to form a coating layer, and - allowing the coating layer to cure at a temperature in the range of -10 to 50ºC. A chemical installation provided with a lining of a cured coating composition as specified above, and a suitable coating composition, are also claimed. It has been found that the coating composition as specified herein has a wide application spectrum, and a high chemical resistance.
