Abstract : A coating composition for protecting metal surfaces from corrosion having controlled proportions of an alkyl ammonium alkyl phosphate and a high molecular weight petroleum sulfonate to inhibit corrosion, silicone and silicone alkyd resins to provide a physical barrier, trichlorotrifluoroethane and an aromatic hydrocarbon as solvents, and isoproply alcohol as a coupling agent. An ethyl cellulose thickener may be added to the composition to increase its viscosity and reduce vertical run-off of the coating. The composition displaces water and moisture on the surface to be coated and deposits a clear, flexible, non-tacky film particularly resistant to abrasion. (Author)
