Patent ID: 7534472

Claim:
A method for treating a metal surface of a subject with an aqueous coating material comprising: (A) providing the aqueous coating material; (B) making an application of the aqueous coating material to the metal surface; (C) removing any excess of the aqueous coating material from the subject; and (D) drying the coated subject; wherein the aqueous coating material comprises water, at least one resin, and at least one emulsifier or surfactant; wherein the resin comprises one or more polymerized C-5 and/or C-9 hydrocarbons and a liquid drying oil wherein the resin is characterized by a density of from about 7.8 pounds per gallon (0.936 kg per liter) to about 8.2 pounds per gallon (0.984 kg per liter), a Gardner Color of 3− to 9+, less than 1% volatile matter after 2 hours @ 100° C., and a viscosity of 600-1700 centipoise wherein said viscosity is measured @ 25° C.; and the aqueous coating material is characterized by a solids content in the range of from about 50% to about 70% by weight, from about 35% to about 55% by volume; a VOC content of not more than 120 grams per liter excluding water; and a viscosity in the range of from about 20 to about 55 centipoise.
