Abstract: Calcium or other sulfonate gel in an oil carrier (such as that of U.S. Pat. No. 4,629,753 to Quinn), optionally mixed with a small amount of sodium sulfonate and tall oil fatty acids, can be neutralized with amine, e.g. DMEA, to form a soap which can be dispersed in water. Adding an acrylic emulsion results in an acrylic coating rich in corrosion-retarding alkali metal or alkaline earth metla sulfonates. This finish on metallurgically roughened, e.g. nitrocarburized, metal forms a firm film which can resist greater than 500 hours ASTM B117 salt spray.

Abstract: Corrosion preventives, e.g. for automobiles, comprise sepiolite clays with waxes, sulfonates e.g. SACI, optional solvents, oils, soaps provide high viscosity, high solids, corrosion-preventatives. Application can be by hot spray or hot melt, hot dipping, and other standard techniques. The sepiolite clays provide excellent anti-sag capabilities to the dry films without excessively increasing the viscosity of the coating material. Conventional thixatropes such as bentonites and other common organo clays usually drastically increase product viscosity and complicate pumping at room temperature.

Abstract: Adding a combination of sterically hindered tertiary amines or derivatives, e.g. piperidine and derivatives, with overbased metal (e.g. calcium, magnesium, barium, zinc, etc.) sulfonate, wax and oxidized petrolatum solvent based rust preventative compositions dramatically increases weather and salt-fog protection.

Abstract: A waterbase coating composition for use in protecting the threads of metal studs during automotive production line phosphating, electrostatic painting and welding. Composition also provides controlled lubricity as well as even torque during the tightening sequency of fasteners by robotics.
