Abstract:
A method for forming in-situ a fluorinated organic compound or polymer film from the friction-induced reaction of an organic material, such as zinc dialkyldithiophosphate (ZDDP), and a fluoridated material, such as iron fluoride (FeF 3 ) on or in proximity to a wear surface substrate. Also disclosed is a method for producing a lubricated wear surface by frictionally reacting an organic material and a fluoridated material near a wear surface, where the reaction product is a fluorinated organic compound bonded to the wear surface.
Abstract:
A coating and bonding composition is disclosed which includes a suspending agent, bonding agent, thinning agent, and a particulate fluoride anti-seize agent designed to bond a particulate fluoride film to the thread surface to prevent seizing and galling. A anti-seize/lubricating composition is also disclosed where an environmentally friendly lubricating composition is applied as a top coat to the bonding composition and to methods for making and using the compositions.

Abstract:
A biodegradable penetrating lubricant, comprised of: (A) at least one triglyceride oil of formula (I), wherein R 1 , R 2 , and R 3 are aliphatic hydrocarbyl groups containing from about 7 to about 23 carbon atoms; (B) an organic solvent selected from the group comprising: (1) ethyl lactate; (2) methyl ester; and (3) combinations of 1 and 2; (C) an antioxidant; and, (D) a corrosion inhibitor. Optionally, the lubricant may further an additive selected from the group comprising: (E) a viscosity modifier; (F) an anti-wear inhibitor; and, (G) an emulsifier.
Abstract:
The present invention is directed to an antimicrobial composition, comprising pyrithione or a pyrithione complex; and a zinc or copper or silver source selected from the group consisting of zinc or copper or silver salts, oxides, hydroxides, sulfates, chlorides, metals, and combinations thereof; wherein the weight ratio of the zinc or copper or silver source to the pyrithione or the pyrithione complex is in the range from about 1:300 to about 50:1, and wherein the antimicrobial composition has an enhanced biocidal effect against a variety of free-living microorganisms or biofilms. Also disclosed is a method of inhibiting the growth of free-living microorganisms or biofilm utilizing the above antimicrobial composition, as well as use of such antimicrobial compositions in various products including fuels, fluids, lubricants, coatings, adhesives, sealants, elastomers, soaps, cosmetics, plastic or woven or non-woven fibers, pharmaceuticals, and as preservatives for the above products.
Abstract:
Lubricating oils exhibiting anti rust-properties are obtained by adding to the lubricating oil an acidic anti-rust additive and an acid scavenger such as carbodiimide, in a specific sequence.
Abstract:
The invention concerns a lubricating composition, in particular for swaging, consisting of a suspension in water of a mixture of phospholipids and an organic or mineral basic compound. For example, the composition contains 80 wt.% water, 10 wt.% phospholipids brought in the form of soja bean lecithin, and 10 wt.% of calcium hydroxide or stearylamine as basic compound. Among other advantages the lubricant can be eliminated by means of an aqueous solvent, and is easily biodegradable.
Abstract:
The invention is a lubricant concentrate composition, use solution, and method of use. The lubricant includes amine compounds of the formula R1 - O - R2 - NH2, R1 - O - R2 - NH - R3 - NH2, and mixtures thereof, wherein R1 may be a linear C6-C18 alkyl, R2 may be a linear or branched C1-C8 alkyl, and R3 may be a linear C1-C8 alkyl, and a corrosion inhibitor. The lubricant composition preferably includes a polycarboxylic acid as a corrosion inhibitor. The composition may also include a hydrotrope, stabilizer, and a surfactant to provide detergency to the composition upon dilution and use. The invention also includes a lubricant use solution resulting from dilution of this concentrate.

Date Nov. 28, 1991.A flame retardant grease composition comprising a lubricating base oil, a thickener selected from a simple or complex soap of lithium, calcium or sodium, and a flame retardant additive selected from an oxide, hydroxide, carbonate, bicarbonate, hydrogen carbonate or sulphate of an alkali metal or alkaline earth metal, for example calcium oxide, potassium carbonate, potassium hydrogen carbonate or potassium sulphate, or a mixture of two or more thereof.
Abstract:
The title lubricant composition comprises a base oil or base grease and a specified amount of a heat insulating agent comprising (A) an inorganic compound undergoing endothermic melting at temperatures of 1200 DEG C or below and (B) an inorganic powder which neither melts nor decomposes at temperatures of 1200 DEG C or below and which has a thermal conductivity of 0.01 cal/cm.s. DEG C or less and a friction coefficient of 0.7 or less at room temperature added alone or as a combination. This lubricant composition has an excellent heat-insulating effect and is effective in preventing occurrence of thermal crown of working rolls.
