Patent ID: 7795326

Claim:
A liquid, polymer-containing coating material comprising about 1 to 50 wt % amphiphilic polymer and about 50 to 99 wt % of a non-stinging, volatile, hydrophobic liquid as part of a solvent system, said amphiphilic polymer being dissolved in said solvent system; wherein the weight percentages are based on the total weight of the liquid, polymer-containing coating material; wherein said amphiphilic polymer comprises at least one polymerizable nitrogen-containing monomer component whose homopolymer is soluble in water and at least one polymerizable siloxy-containing monomer component that is hydrophobic; wherein said liquid coating material forms an adherent, conformable, water-vapor permeable, water-insoluble coating when applied to a surface, wherein the amphiphilic polymer comprises about 15 to 85 mole % polymerizable nitrogen-containing monomer component and about 15 to 85 mole % polymerizable siloxy-containing monomer component; and wherein said non-stinging, volatile, hydrophobic liquid is a non-stinging, volatile, hydrophobic liquid selected from the group consisting of volatile linear and cyclic siloxanes, volatile alkanes, volatile fluorocarbons, liquid and supercritical carbon dioxide, and mixtures thereof.
