The present invention relates to a curable coating composition, comprising: (a) a curable coating resin comprising thiol-reactive groups, (b) a thiolated norbornene curing agent for the curable coating resin, the thiolated norbornene curing agent comprising on average at least 1.0 thiol group per molecule, and (c) an accelerator for accelerating the reaction between the thiol reactive- groups on the curable coating resin and the thiol groups on the thiolated norbornene curing agent. These coating compositions can be cured at ambient temperature and provide a coated surface that can be walked on after only a couple of hours. The coating compositions in general have a VOC below 250 g/L. The coating compositions can be used for the protection of large steel structures, such as ships, buildings, bridges, industrial plants, and oil production installations.
