Patents Assigned to Cincinnati Vulcan Company
  • Patent number: 5001013
    Abstract: Coating oil compositions are provided which contain an oil-soluble metal petroleum sulfonate, an oxidate ester, an organic acid ester, and a hydrocarbon oil. The coating oils are highly effective for preventing rust and corrosion of both ferrous and non-ferrous metals but are particularly advantageous for application to metal sheet which is subsequently to be electrocoated. Coating oils formulated in accordance with the present invention exhibit improved electrocoat compatibility.

  • Patent number: 4885104
    Abstract: Improved metalworking lubricants derived from natural fats and oils and obtained by reacting the natural fat or oil with a hindered polyol and a dicarboxylic acid are provided. These lubricants may be chlorinated, sulfurized or chlorosulfurized. Also disclosed are compositions useful for a variety of metalworking applications wherein the modified triglyceride is blended with conventional triglycerides and/or hydrocarbon oils and which may additionally contain emulsifiers and additives.

  • Patent number: 4675125
    Abstract: Improved multi-purpose metal cleaning compositions are provided comprised of 5 to 40 parts by weight ethoxylated aliphatic alcohol or ethoxylated alkylphenol, 4 to 20 parts by weight alkanolamine salt of a fatty acid, 2 to 15 parts by weight boramide, 2 to 15 parts by weight alcohol, glycol or ether glycol, 0.05 to 2.5 parts by weight antifoam agent, and 5 to 98 parts by weight water. In addition to being highly effective cleaners for the removal of grease, oil, dirt, scale and metal fines, the compositions of this invention also provide a non-sticky and non-greasy corrosion-resistant protective barrier on the surface of the metal.

  • Patent number: 4395286
    Abstract: A water-based coating composition which upon drying prevents rust and corrosion on metal surfaces, but does not leave a waxy film upon the coated article. The coating composition is a mixture of a monovalent metal or amine, salt of a sulfonic acid, a polybasic fatty acid, an alkanolamide, a water soluble ether and water. The coating oil is a substitute for hydrocarbon-based coating oils and provides the rust protection and corrosion resistance of a hydrocarbon-based coating oil but does not cause a waxy buildup. This water-based coating is also more biodegradable and substantially safer than a hydrocarbon-based system.

  • Patent number: 4359393
    Abstract: This invention relates to water active metalworking lubricant compositions, particularly for the cold rolling of aluminum and other sensitive non-ferrous metals and alloys. Water emulsions or solutions of the lubricant composition provide good lubricity and anti-wear properties and furthermore, prevent water staining of aluminum. The water active lubricant composition contains (a) an alkanolamine salt of a C.sub.36 dimer or C.sub.54 trimer acid, (b) an aliphatic monoalcohol or monocarboxylic acid and (c) an alkyl ester of a fatty acid.
