A lubricant composition with improved stability and tolerance for water hardness comprises a synthetic wax emulsion; an amine derivative; an emulsifier; and a sequestrant. The synthetic wax emulsion may include poly(ethyleneoxide)-based or poly(propyleneoxide)-based wax emulsions. The amine derivative may include alkyl C.sub.12-C.sub.14 oxy propyl diamine. The lubricant composition can be used for lubricating the passage of a container along a conveyor. The method includes applying the lubricant composition to at least a part of the container or the conveyor in an application cycle, where the application cycle includes a first period of time of dispensing the lubricant composition and a second period of time of not dispensing the lubricant composition.

A booster additive concentrate may advantageously contain: (a) an anti-wear mixture of two or more phosphite/phosphate compounds and one or more ether/thioether compounds; (b) an ashless dispersant; (c) a calcium-containing detergent, such as an overbased calcium phenate; (d) ≥2 friction modifiers, at least one of which comprises a polyalkylene polyamine succinimide derivative; (e) optionally a corrosion inhibitor; and (f) a lubricating oil basestock. Based on these additive components, the booster additive concentrate may exhibit specific contents of B/Ca/P and may contain minimal or substantially no additional antioxidants. Lubricant compositions can be made from the booster additive concentrates and a fresh/used lubricant oil composition “diluent,” which can rejuvenate the diluent. Such lubricant compositions can have advantageous anti-shudder durability (ASD) lifetimes and other frictional properties. In particular, such concentrates/compositions can offer superior lubrication when used in vehicles with continuously variable transmissions (CVTs).

A gear lubricant composition includes at least 97% by weight, based on the total weight of the lubricant composition, of at least one hydrocarbon-based oil that includes a weight content of isoparaffins ranging from 90 to 0%, a weight content of normal paraffins ranging from 0 to 10% and a carbon content of biological origin greater than or equal to 90% relative to the total weight of the oil, at least 0.01% by weight, based on the total weight of the lubricant composition, of at least one additive selected among the anti-wear additives, extreme pressure additives, anti-corrosion additives, additives having metal-deactivating properties, anti-foam additives, anti-oxidant additives selected among the phenolic anti-oxidants, and the mixtures thereof.

A lubricant includes at least 45 wt % paraffin oil, less than 8 wt % of a pyrophosphate or triphosphate, more than 6 wt % of a group 6 disulfide or diselenide and up to 27.5 wt % of graphite. The lubricant is used in a method for producing a magnesium alloy tube via extrusion, and is especially useful to form implants such as stents while maintaining the biocompatibility of the magnesium alloy.

The present invention concerns a coolant, present as an emulsion in the form of a concentrate, for machining fiber-reinforced plastics and material combinations containing fiber-reinforced plastics and metals; furthermore, the present invention also concerns a coolant, present as a solution in the form of concentrate, for machining fiber-reinforced plastics.

A lubricating composition which, when used with a device for clamping an article, such as a chuck, produces excellent lubricating properties whilst remaining strongly adhered to metal parts in a clamping mechanism of the device and showing enhanced chemical and physical resistance to fluids such as cutting fluids.

A plunger lubricant for die casting includes a component (a), a component (b), a component (c), and water. The component (a) is one or two or more compounds selected from among mineral oils, synthetic hydrocarbons, and fatty acid esters. The component (b) is one or two or more compounds selected from among alkali metal salts of higher fatty acids or alkali metal salts of aliphatic hydroxy acids. The component (c) is an alkali metal salt of an oxoacid or polyoxoacid that is able to be dehydrated and condensed.

Lubricant composition, in particular a cooling lubricant solution, based on ionic and/or organoelemental compounds.
