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 R 2 , R 3 , R 4 and R 5 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:
This invention discloses novel catalyzed surface coating additives and catalyzed surface coating systems, 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 coating films which may exhibit pigmentation and other aesthetic features, and may be designed to be environmentally benign.
Abstract:
The invention relates to a lubricant which contains solid particles that are dispersed in an organic matrix and have a mean particle size of between 1 and 500 nm. The lubricant preferably contains between 0.05 and 30 % by weight, in relation to the total formulation, of solid particles. The organic matrix is preferably selected from among native or mineral oils or fats, carboxylic acid salts with between 12 and 44 carbon atoms, waxes and organic polymers. The solid particles are preferably selected from the metal oxides, metal hydroxides, metal nitrides, metal carbides, metal phosphides, metal borides and metal sulfides and preferably have a hydrophobic coating. The above lubricants can be used to lubricate parts moving in relation to each other, as forming aid, cutting fluid and rolling oil emulsion.
