CORROSION-RESPONSIVE COATING FORMULATIONS FOR PROTECTION OF METAL SURFACES

摘要

Methods and compositions are described for protecting a metal surface agains t corrosion. The method involves applying to the metal surface a coating formulation that comprises a radiation curable resin and a corrosion- responsive agent that is capable of releasing a corrosion-inhibiting ion in response to exposure to ionic species characteristic of those present on a metal surface undergoing oxidative corrosion; and exposing the coating formulation to radiation whereby the radiation curable resin forms a corrosi on- resisting coating having a low spontaneous release rate of the corrosion- responsive agent into the environment.
