ABSTRACT:
A process of employing a coating to control toxicant leaching rate of a marine antifouling paint and thus, to extend its useful lifetime is disclosed. An ambient-temperature curing system is made from water soluble or dispersible hydantoin epoxy resins, a water dispersible polyamido amine, and optionally with an inhibitor, an accelerator and a swelling agent. A water swellable, thermoset coating which is permeable to antifouling compounds results.
