Abstract:
Low viscosity functional fluids are described which comprise glycols and an additive package that includes a fatty acid and a phosphate ester, such as a phosphate ester of an alkyl, alkenyl, or aryl alcohol. The fluids are particularly well-suit for use as DOT 3 or DOT 4 brake fluids and provide robust lubricity and corrosion inhibition.
Abstract:
The fluid compositions of the present invention include an glycol component that includes a mixture of glycols according the formula: Wherein, typically, at least one of R2, R3, R4 and R5 is an alkyl group. The physical properties of the compositions include a high dry equilibrium reflux boiling point (ERBP), a high wet equilibrium reflux boiling point (WERBP), a low temperature viscosity or any combination thereof. These compositions are particularly useful because their physical properties (e.g., WERBP, ERBP, and low temperature viscosity) meet or exceed the provisions for DOT 3, 4, or 5 brake fluids.
Abstract:

A method of producing a nanoparticle by milling layered materials is provided. Also disclosed is a method of making a lubricant, the method including milling layered materials to form nanoparticles and incorporating the nanoparticles into a base to form a lubricant.
Abstract:
A conveyor lubricant including an effective lubricating amount of at least one lubricant and at least one protectant which is an alkanolamide, alkyl ether sulfonate, acetylenic diol, alkyl ether carboxylic acid or salt thereof, alkylated diphenyl oxide disulfonic acid or salt thereof or a mixture thereof, and methods of using the same.
Abstract:
This invention provides phyllosilicates and polyfunctional dispersants which can be manipulated to selectively control the viscosity of phyllosilicate slurries. The polyfunctional dispersants used in the present invention, which include at least three functional groups, increase the dispersion and exfoliation of phyllosilicates in polymers and, when used in conjunction with phyllosilicate slurries, significantly reduce the viscosity of slurries having high concentrations of phyllosilicates. The functional groups of the polyfunctional dispersants are capable of associating with multivalent metal cations and low molecular weight organic polymers, which can be manipulated to substantially increase or decrease the viscosity of the slurry in a concentration dependent manner. The polyfunctional dispersants of the present invention can also impart desirable properties on the phyllosilicate dispersions including corrosion inhibition and enhanced exfoliation of the phyllosilicate platelets.

The disclosure relates to improved gel/grease compositions as well as grease compositions capable of imparting improved corrosion resistance. The grease includes a silica/silicate mixture that can imparts a relatively high pH and corrosion resistant properties to the grease.
Abstract:
This invention discloses novel catalyzed surface composition altering formulations and methods and catalyzed surface coating formulations and methods, which contain one or more catalysts, along with optional other ingredients, wherein the catalysts serve to effect in situ chemical bonding reactions in that the catalysts function to initiate, to promote, to accelerate, and/or to increase the formation and yield of persistent, solid, corrosion-resistant, impact-resistant, wear-resistant, and/or non-stick surface compositions and surface coating films, which may exhibit pigmentation and other aesthetic features, and may be designed to be environmentally benign. The disclosed formulation and methods may be used to alter the surface composition and to coat the surfaces of vehicles, such as aircraft, and to improve the anti-icing characteristics of the vehicle surfaces.
Abstract:
A lubricating composition containing an organic molybdenum compound having excellent oxidation stability that provides lubricity for long periods of time is provided. The lubricant comprises a molybdenum amine compound obtained by reacting a compound containing a hexavalent molybdenum atom with an amine represented by the following formula (1): wherein each of R1 to R3 represents a hydrogen atom and/or a hydrocarbon group, and at least one of R1 to R3 is a chain hydrocarbon group having 14 or more carbon atoms; or the following formula (2) wherein R4 represents a chain hydrocarbon group having 10 or more carbon atoms, s represents 0 or 1, X and/or Y represents a hydrogen atom, a hydrocarbon group, an alkanol group or an alkyl amino group having 2 to 4 carbon atoms, and X and Y are not hydrogen atoms or hydrocarbon groups at the same time when s is 0. A lubricating composition containing the lubricant is also provided.

Abstract:
A water-soluble cutting fluid which is characterized by excellent cooling and lubricating properties and does not exert a harmful influence on the environment. A solution containing hydrogencarbonate ion, bromide ion, carbonic acid ion, and, if necessary, fluoride ion, and being adjusted to a pH of 7.0 to 11.5 can be used as a substitute for a cutting oil. A water-soluble cutting fluid further including additives such as rust-preventive agents and the like can be also used as a substitute for conventional cutting oil.
