Liquid coating compositions comprising (a) carbon nanotubes, (b) at least one fluorinated polyurethane or a urethane polymer modified with a perfluoroalkylsulfonamide, (c) a resin binder, and (d) a solvent, are used as ingredients. A single ingredient may be both a component (b) and component (c) or component (b) and component (c) may independently be separate ingredients. The composition optionally comprises (e) at least one silicone and/or at least one siloxane. The resin binder is selected from alkyds, acrylics, vinyl-acrylics, vinyl acetate/ethylene, polyesters, melamine resins, epoxy resins, polyurethanes and mixtures thereof. The solvent is a combination of water and alkyl ether of ethylene glycol. The carbon nanotubes are single-walled carbon nanotubes, with a length-to-diameter ratio of 50:1 to 500:1. The composition may additionally comprise an anti-fungal, anti-algae or anti-microbial ingredient. |
