The present invention relates to a lubricating composition for an engine, in particular for a motor vehicle engine, comprising at least one base oil and at least one compound able to release formaldehyde under the temperature and pressure conditions of the combustion chamber of the engine. It also relates to the use, in a lubricating composition intended for an engine, of a compound able to release formaldehyde under the temperature and pressure conditions of the combustion chamber of the engine, as an additive for preventing and/or reducing pre-ignition, in particular low-speed pre-ignition (LSPI).

The present invention relates to a belt lubricant concentrate comprising 15% by weight to 30% by weight of at least one monocarboxylic acid, 10% by weight to 25% by weight of at least one N-alkyl-1,3-propanediamine, 5% by weight to 15% by weight of at least one nonionic surfactant and water up to 100% by weight.

Anaerobic sealant lubricant compositions and uses are disclosed. The anaerobic sealant lubricant compositions cure anaerobically but have lubricity for easy disassembly, making the compositions well suited for fasteners and threaded components.

An entry sheet for drilling comprising: a metallic foil; and a layer of a resin composition on at least one surface of the metallic foil, the resin composition comprising a polyolefin resin (A) and a water-soluble resin (B), wherein a content of the polyolefin resin (A) is 25 parts by mass or more and 50 parts by mass or less based on 100 parts by mass of the total of the polyolefin resin (A) and the water-soluble resin (B), a content of the water-soluble resin (B) is 50 parts by mass or more and 75 parts by mass or less based on 100 parts by mass of the total of the polyolefin resin (A) and the water-soluble resin (B), and the water-soluble resin (B) comprises a high-molecular-weight water-soluble resin (B-1) having a weight average molecular weight of 2×10.sup.5 or higher and 1.5×10.sup.6 or lower.

The present application relates to biodegradable zero drip lubricating oil composition. The lubricating oil composition comprises a) an oil soluble polyalkylene glycol polymer; b) a vegetable base stock; and c) organic solvent excluding alcohol, wherein the oil soluble poly alkylene glycol and the vegetable base stock are present in a weight ratio from 1:2.6 to 1:8. The biodegradable lubricating oil compositions have high film strength, high load carrying capability, zero anti-drip property and maximum penetrability in the chain linkages, for application in roller chains and driving power trains having complex chain linkages.

The disclosed technology relates to a traction fluid containing a base fluid having at least one of cedrene, cedrol, thujopsene or mixtures thereof, preferably provided from cedar oil, as well as a method of lubricating a power transmission apparatus with the traction fluid.

Brine-tolerant lubricants are provided. The brine-tolerant lubricants may comprise an oil component, a surfactant component, and, optionally, an additive component. In one aspect, the oil component comprises a fatty acid alkyl ester. In one aspect, the surfactant component comprises at least one of an alkoxylated fatty acid and an alkoxylated fatty alcohol. Also provided are methods for increasing the lubricity of a drilling fluid by contacting the drilling fluid with the brine-tolerant lubricants.
