A polymer containing an isocyanatoalkyl ester of an unsaturated carboxylic acid and optionally, another addition polymerizable monomer, is cross-linked using water as a curing agent. Water may be mixed into the composition or transmitted to the polymer by the atmosphere. The cross-linked polymer forms a solid, insoluble coating material which is useful as an industrial coating.

Moisture curing of polymer coating compositions containing

Curable compositions containing (1) an epoxy resin containing a plurality of active hydrogens and (2) and addition polymer of an isocyanatoalkyl ester of an .alpha., .beta.-ethylenically unsaturated carboxylic acid such as 2-isocyanatoethyl methacrylate are usefully employed as coatings for metal substrates and in other applications which require hard surface coatings exhibiting resistance to chemicals and light.
