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 BX1X2X3, wherein X1, X2, and X3 are independently selected from —Y1 and —OY2, wherein Y1 is independently selected from monovalent C1-C12 alkyl groups and monovalent C6-C12 aryl groups, and Y2 is independently selected from monovalent C1-C12 alkyl groups and monovalent C6-C12 aryl groups, and wherein at least one of X1, X2, and X3 is an —OY2 group,—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 0 to 50° C. 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 compos…
