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.

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.

Abstract: Useful oil compositions for coating ferrous and non-ferrous metals are provided. The coating oils are blends of a petroleum sulfonate, polymeric fatty acid and hydrocarbon oil.

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.

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.

Abstract: This invention relates to useful protective compositions, a method for protecting aluminum and aluminum alloy products against water staining, and a protected aluminum sheet. The method involves applying a continuous film of a protective composition to the surface of the aluminum product. The protective compositions useful for the invention are blends or reaction products of a polybasic acid and a partial ester of a polyol.

Abstract: Amino-amides obtained by the reaction of polymeric fatty acids with poly(oxyethylene) diamines are readily compatible with water in all proportions and form clear, aqueous solutions which have excellent lubricating properties.

Abstract: Mixed ester products obtained by treatment of a triglyceride under transesterification conditions with a polyoxyalkylene glycol and a high molecular weight dicarboxylic acid, such as polymer acids, are useful metal working fluids. The modified triglycerides exhibit enhanced thermal stability and can be used either in neat form or in solution and are readily compatible with water to provide stable aqueous emulsions and dispersions having superior lubrication properties.

Abstract: Water soluble mixed ester lubricants derived from triglycerides are obtained by transesterifying a triglyceride with a low molecular weight polyoxyethylene glycol in the presence of short-chain mono- or dicarboxylic acids. The mixed ester compositions of this invention are readily water soluble and are excellent lubricants for metalworking operations. Water solubility is achieved with the present mixed ester products even though they have higher triglyceride contents than previously known ester lubricants.

Abstract: Ester lubricant compositions are provided which provide a good balance of lubricity and emulsifiability. The esters are derived from polyoxyalkylene glycols with a dibasic acid mixture consisting of dimer acids and short-chain dibasic acids. The emulsions and clear, homogeneous lubricant solutions provide excellent spin finishes for fibers such as polyamides and polyesters.
