Abstract:
An aqueous coating composition forming a magnetic coating layer. The composition is improved over prior art magnetic coatings by the inclusion of a colloidal emulsion of a lubricant, such as, for example, a member selected from the group consisting of aliphatic and aromatic stearates, silicone oils, perfluoro alkyl polyethers and fluorinated fluids.
Abstract:
The disclosure concerns an aqueous lubricant composition, characterized in that it comprises of: 50wt % of water, 0.01-20 wt % of a thickening agent, 0.5-10 wt % of an antioxidant; 0.5-5 wt% of a pH regulating agent; and glycerol. There is also provided a method for manufacturing the aqueous lubricant composition, and uses of said aqueous lubricant composition.

Abstract:
A metal glycol-based hydraulic fluid having vapor phase corrosion inhibition properties is disclosed. The hydraulic fluid can be used in food related applications.
Abstract:
The present invention relates to a method of lubricating a conveyor belt wherein a lubricant concentrate containing at least one oil is employed in a dry lubrication process. Afterwards, a liquid composition having a pH-value ≥ 5 is applied to the surface of the conveyor belt on which the lubricant concentrate has been applied earlier.
Abstract:
The present invention provides a water based friction control composition comprising a binder a rheological control agent, and optionally a lubricant. The liquid friction control composition may also comprise other components such as a wetting agent, a consistency modifier, and a preservative. The liquid friction control compositions may be used to modify the interfacial friction characteristics in sliding and rolling-sliding contact such as steel wheel-rail systems including mass transit and freight systems. A method of reducing lateral force, reducing energy consumption, or controlling friction between a metal surface and a second metal surface by applying the composition to metal surface, for example a top of rail or wheel, is also provided. The composition may be sprayed onto the rail surface.
Abstract:
A first treating agent for forming a protective coating which comprises water and, compounded therewith, an alkali silicate represented by the formula: M2O . nSiO2, wherein n represents a number of 2 to 9 and M represents at least one of Na, K, Li and NR4 where each R independently represents a hydrogen atom or an alkyl group a second treating agent comprising the first treating agent and a lubricating agent a metallic material having a protective coating formed by using the treating agent and a method for forming a protective coating which comprises using the treating agent. The second treating agent can form a coating film having excellent self-lubricating property. The treating agents can form a coating film having excellent anti-galling and rust preventive properties which is comparable or superior to those of a coating film formed through a chemical reaction of a metallic base material, by a simple and easy method wherein the treating agent is applied on the surface of a metallic material and then dried.
Abstract:
A lubricant in the form of an oil- insoluble solvent e.g. water in oil emulsion is described where a water soluble or water dispersible base is present in the dispersed phase. These lubricants are beneficial in various applications such as internal combustion engines where the oil desirable has enough basicity to neutralize any inorganic acids generated by sulfur present in the fuel.
Abstract:
La présente invention a pour objet un procédé de laminage à froid de métaux mettant en oeuvre un lubrifiant aqueux comprenant (1) au moins un mélange à base d'au moins un acide choisi parmi les acides mono- ou poly-carboxyliques, saturés ou non, comprenant 5 à 40 atomes de carbone; d'au moins un ester phosphate acide de formule (RO) x -P(=O)(OH) x' , formule dans laquelle R est un radical hydrocarboné, éventuellement polyalcoxylé, x et x' étant égaux à 1 ou 2, à la condition que la somme de x et x' soit égale à 3; l'acide carboxylique et/ou l'ester phosphate acide étant éventuellement neutralisé(s) par une base organique ou minérale; et (2) au moins une cire naturelle ou synthétique présentant un point de fusion supérieur ou égal à 50 °C et présentant une taille moyenne de particules comprise entre 0,5-10 μm. La mise en oeuvre de ce lubrifiant permet d'augmenter la productivité du procédé d'au moins 15 % par rapport à un procédé mettant en oeuvre un lubrifiant classique.
Abstract:
A lubricant coating disposed between a substrate and a counter surface comprises a reaction layer immediately adjacent the substrate. A bonding layer is immediately adjacent the reaction layer, with the bonding layer comprising a first composition. A low friction, lubricious layer is immediately adjacent the bonding layer, with the lubricious layer comprising a second composition that is different from the first composition.
