ABSTRACT:
Disclosed is an improved marine anti-fouling coating composition of a thermoplastic binder, an organic solvent, a tin anti-fouling agent, a copper anti-fouling agent, and a water-soluble leaching agent. The improvement in can stability for said coating composition comprises the leaching agent being a water-sensitive, solvent soluble non-cross-linked polymer having an acid number of below about 50 and a .chi. value of between about 0.1 and 0.3; or a water-sensitive, solvent soluble, polymer having an acid number of below about 50 and a .chi. value between about 0.3 and 0.6. The water sensitive solvent insoluble polymer may be a non-cross-linked oligomer or polymer or a cross-linked hydrogel possessing the requisite acid number and .chi. value restriction.
