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 coating composition comprising epoxy-functional resin, and amine curing agent for the epoxy-functional resin, wherein the coating composition comprises an organic silicon-containing compound selected from the group of organosilanes and organosiloxanes, with the molar ratio between the silicon atoms of the organic silicon-containing compound and the epoxy-groups in the coating composition being in the range of 0.20-0.75:1.00, —applying the coating composition to a metallic or concrete 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. The invention also pertains to a chemical installation comprising a metallic or concrete surface provided with a lining of a cured coating composition and to a coating composition suitable for providing a metallic or concrete surface of a chemical installation with a coating. It has been found that the coating composition of the present invention shows a wide application spectrum and a high chemical resistance.
