Abstract
A biocidal protective coating for heat exchanger coils formed by applying a polymeric composition containing an organic water resistant polymer that has associated with it an effective amount of a biocidal compound to inhibit corrosion, fouling, and biocidal buildup on the coils.
Claims24
A heat exchanger, comprising an exterior coating comprising:
- (a) a water resistant organic polymeric material comprising a halogenated polymer, and wherein the material bonds to the surface of the heat exchanger;
- and
- (b) an effective amount of poly(iminoimidocarbonyl) iminoimidocarbonyl iminohexamethylene hydrochloride, sufficient to inhibit growth of microorganisms on the heat exchanger.
A method of protecting a heat exchanger coil comprising coating the coil with a polymeric composition comprising a water resistant organic polymeric material comprising a halogenated polymer, and wherein the material bonds to the surface of the heat exchanger;
- and an effective amount of 2-N-octyl-4-isothiazolin-3-one sufficient to inhibit growth of microorganisms on the heat exchanger.
