摘要： A water-based coolant contains: at least one inorganic acid salt selected from among carbonate, hydrogen carbonate, sesquicarbonate, phosphate, borate, molybdate and tungstate; and a metal corrosion inhibitor. The water-based coolant is excellent in cooling performance and unlikely to cause corrosion of a metal material to be cooled. Therefore, the water-based coolant is suitably usable as a quenchant or a cutting oil.

摘要： Disclosed is a refrigerator oil composition comprising at least one base oil selected from mineral oils and synthetic oils, and at least one polyether compound having a kinematic viscosity of from 200 to 10000 mm /sec at 100 DEG C. The composition has an excellent lubricating property, while specifically improving the lubricity of bearings. This is effective for preventing bearings from being seized and fatigued, and is suitable as a lubricating oil in refrigerators using hydrogen-containing Flon refrigerants, such as R134a, that do not cause environmental pollution.

摘要： A water-based coolant contains at least one inorganic acid salt of phosphate, phosphite, sulfate, sulfite, borate, molybdate, tungstate, carbonate, hydrogen carbonate and sesquicarbonate. Since the water-based coolant of the invention exhibits a high cooling capability but does not easily corrode a metallic material (a cooling object), the water-based coolant of the invention is suitable as a quenching oil or a cutting oil for the metallic material.

摘要： Provided is a novel additive composition containing (a) a compound having, in the molecule, a group of a general formula (I): wherein R , R and R each represent a hydrogen atom or a methyl group, but at least one of R and R is a hydrogen atom, and (b) an extreme-pressure improver containing sulfur and/or phosphorus, and optionally, as an additional component (c), an extreme-pressure improver containing neither sulfur nor phosphorus. Lubricating oil compositions comprising the additive composition have high load carrying capacity, and are effectively used as metal working oils and hydraulic oils, such as forging oil, pressing oil, drawing oil, rolling oil, cutting oil, grinding oil, etc.
