Provided is a heat-treatment oil composition that makes it possible to suppress quenching distortion and distortion variation and to achieve improved quenching hardness. A heat-treatment oil composition that includes a base oil (A) and a vapor film rupturing agent (B). The heat-treatment oil composition makes it such that, on a cooling curve obtained in accordance with the cooling performance test method in HS K2242:2012, the time in seconds to 300 C., e.g., the cooling time from 800 C. to 300 C., is at least 6.5 seconds but less than 10 seconds. Component (B) includes a petroleum resin.

A dispensable grease sealant includes a base component in an amount of 50 wt % or more, based on a total weight of the sealant, and a thickener. The base component is selected from a group including a silicone wax, a liquid rubber, and a combination thereof.

The invention provides a grease composition used for lubricating a mechanical part having a steel portion to be lubricated which performs a rolling motion and a rolling and sliding motion, containing a base oil, a thickener and an additive, wherein the additive includes at least one compound selected from the group consisting of polyethylene wax, oxidized polyethylene wax, polypropylene wax, montan wax and amide wax.

Provided is a water-based lubricating coating agent for a metal material, capable of carrying out a chemical conversion treatment and a lubrication treatment at the same time, which makes it possible to achieve excellent lubricity even in plastic working, press molding, and the like, and at the same time, operability (e.g., process shortening, sludge reduction). The water-based lubricating coating agent having pH of 2.0 to 6.5 for a metal material is obtained by blending: at least one lubricating component other than black-based solid lubricants; and at least one chemical conversion component selected from the group consisting of a phosphoric acid compound, an oxalic acid compound, a molybdic acid compound, a zirconium compound, and a titanium compound, the concentration of the lubricating component is 5 mass % or more in mass ratio to the total solid content mass in the lubricating coating agent, and the concentration of the chemical conversion component is 0.3 to 8 mass % when the total mass of the lubricating coating agent is regarded as 100 mass %.

The present invention is directed to aqueous compositions with wax and graphene. These compositions offer surprising benefits in reducing bicycle or motorbike chain lengthening, particularly in off road environments with high dirt and water levels such as during mountain biking or off-road biking. The invention is further directed to a method of preparing such compositions and to the use of such compositions on bicycle or motorbike chains.
