Abstract:
Residues resulting from the distillation of fatty acids obtained from fat-splitting processes are converted by the process of this invention to useful metal working lubricants. The present process utilizes distillation residues, which are typically viscous oils ranging in color from dark brown to black and which heretofore had little or no commercial value and were burned or otherwise disposed of, to produce lubricants having performance characteristics which make them suitable for use in continuous metal-casting and other metal working operations.
Abstract:
A surface treatment composition for metal working comprising 10 to 50 parts by weight of a water-soluble thermoplastic synthetic resin having an average degree of polymerization of 300 to 1,700, 40 to 180 parts by weight of an aqueous dispersion of an alkaline earth metal soap and 0.5 to 12 parts by weight of at least one volatile corrosion inhibitor, which can give to a metal panel excellent deep drawing processability, chemical treatment property, rust corrosion resistance or the like.
Abstract:
A lubricant for use with a pneumatic tire wheel assembly containing a run-flat device to permit the tire to run at least 50 miles at 50 miles per hour in the deflated condition, the lubricant comprising a mixture of 2 to 60 parts of fatty acid having from 12 to 24 carbon atoms, 0 to 45 parts metal soap of a fatty acid having from 12 to 24 carbon atoms and 40 to 92 parts of a carrier such as water or a polyol having a carbon to oxygen ratio less than 4 to 1.
WHERE Z IS A BRIDGING ETHER, ESTER OR ALKYLENE GROUP AND $(X+Y)=0-20 AND AQUEOUS INORGANIC AND ORGANIC COLLOIDIAL SOLS STABLE AT ALKALINE PH. THESE COMPOSITIONS CURE THERMALLY TO FORM WATER-INSOLUBLE COATINGS WITH THE COLLOIDAL PARTICLES DISPERSED THROUGHOUT A BINDER MATRIX OF POLYMERIZED ZWITTERIONIC MONOMER. COATINGS OF UNUSUAL HARDNESS, SCRATCH RESISTANCE, FLEXIBLE, RESILIENCE AND LUBRICITY CAN BE OBTAINED USING SOLS OF SUCH MATERIALS AS SILICA, POLYTETRAFLUOROETHYLENE, POLYETHYLENE, STYRENEBUTADIENE LATEX, AND WATER-INSOLUBLE OILS.
Abstract:
A metal working lubricant which can be used for drawing and ironing of sheet stock as well as used as a mechanical lubricant such as a hydraulic oil in the associated metal working equipment comprises a combination of a carboxylic acid; a film forming and wetting agent which comprises a long chain mono or diester of a carboxylic acid; a non-ionic, non-metallic ester or ether emulsifier; and a mineral oil. The viscosity of the lubricant should be at least 250 Saybolt seconds (SSU) and the lubricant, when emulsified, should preferably have an acidic pH.
Abstract:
Ester lubricants derived from high molecular weight dibasic acids, polyoxyalkylene glycols and monofunctional aliphatic alcohols are provided. These ester compositions are useful as lubricants and are readily emulsifiable with water. Aqueous emulsions of these esters have superior lubricating and rust inhibiting properties.

Abstract:
A substantially neutral aqueous lubricant comprising a major portion of water, a polyelectrolyte acrylate compound, a fatty acid compound, a polyalkyleneoxide compound and a C.sub.1-6 alcohol, methods to make the lubricant and methods of its use.
Abstract:
Since primers can be applied to metal substrates prior to subsequent operation, including metal deformation, they are often applied in coil coating operation. The potential for the removal of primer coating during metal deformation is a drawback to early coating application. There is now provided a lubricant composition particularly adapted to meet this problem. The composition comprises metallic stearate, emulsifier, titanium dioxide and Xanthomonas hydrophilic colloid, all in aqueous medium.
