Abstract:
The present invention provides a lubricating oil composition for reducing a friction coefficient adjacent to the surface of being subjected to lubrication. In particular, the present invention provides nanoporous particles capable of being dispersed in a lubricating oil composition comprising base oil having a lubricant viscosity. Since the nanoporous particles having nano-sized, oil soluble pores according to the present invention reduces a friction coefficient, and in the long term, gradually releases an effective ingredient, the lubricating oil composition comprising the same of the present invention can act as a reducing agent for reducing friction for a long period of time, and thereby, exhibit excellent lubricant effects.
Abstract:
The present invention relates to a non-hydroxide grease composition comprising a base oil and a thickener which comprises amorphous hydrophilic silicon oxide particles and one or more metal salts of different organic acids, wherein the silicon oxide particles have a BET specific surface area of at least 50 m2/g and wherein the amount of the metal salt(s) is 4- 25% by weight, based on the total weight of the grease composition. The present invention further relates to a method for manufacturing said grease composition and the use of said grease composition for lubricating a bearing and in couplings and gearings.

Abstract:
An additive for an aqueous metalworking fluid (MWF) comprises a C12-20 fatty acid neutralized with at least one of an amine, alkanolamine and a caustic. The additive is designed for use in an aqueous MWF having a pH of at least about 7 and comprising at least about 0.10 weight percent, based on the weight of the MWF, of the neutralized C12-20 fatty acid. The additive inhibits the staining of ferrous and nonferrous metals during and after machining.
