A lubricant composition includes a base lubricant and a plurality of lubricant additive molecules. Each molecule includes a surface active group attractable to a target surface, wherein the surface active group comprises a carboxyl group, a siloxyl group, an amine group, or a mixture thereof, and a carbon containing component connected to the surface active group, wherein the carbon containing component comprises a carbon ring, wherein the surface active group and the carbon containing component are adapted such that the carbon film is formed in situ on the target surface of the target machine only when tribological energy activates the lubricant additive to unravel the carbon containing component under a pressure and a temperature during operation.

Hydrophilic coatings including a base coat layer and a top coat layer wherein at least one of the base coat and top coat compositions that form the hydrophilic coatings comprises a diacrylate compound have a number average molecular weight less than 1000.

The invention relates to industrial gear oil compositions that have been specially designed to have improved storage stability and/or paint compatibility and/or seal compatibility. This improvement is achieved while maintaining good performance in other areas. These improvements are particularly relevant to synthetic lubricants, such as those made with polyalphaolefin (PAO) base oils. This balance of properties has been difficult to achieve in synthetic compositions where problems in the areas of storage stability, paint compatibility and/or seal compatibility of become more pronounced. The invention also relates to processes of making such compositions and methods of using the same.

The present invention belongs to the field of lubricant technologies, and specifically, to a sulfur-and phosphorus-free extreme pressure lubricant and a preparation method thereof. In the present invention, the lubricant prepared by using Turkey red oil, a cyclic anhydride compound, triethanolamine, nano polytetrafluoroethylene powder, an alcohol compound, and water as raw materials does not contain hazardous substances such as sulfur and phosphorus. This reduces the harm to the environment, equipment, and human body, and conforms to the development trend of modern industrial production. Moreover, the lubricant has excellent extreme pressure performance, and can effectively reduce the downhole friction and torque, thereby meeting the construction requirements of extended reach wells and horizontal wells.

The present invention describes a chemically-assisted machining process that converts conventional lubricant chemistries to produce reactive oxygenated species that accelerate the formation of friction-reducing boundary layer lubrication during cutting operationstermed Ozonolytic Machining. The new type of cooling-lubricant chemistry is based on chemical reactions between unsaturated bio-based oils and alcohols, and other types of machining lubricants, containing carbon-carbon double or triple bonds, with ozone gas to form variously reacted or polymerized ozonidestermed super-oxygenated fluids, oils or alcohols, aldehydes or ketones, sulfurized ozonides and super-oxygenated gels.

A gun oil composition adapted specifically for the needs and requirements of modern firearms. The gun oil composition improves lubricity and gun performance under normal and extreme heat and pressure, minimizes and largely prevents the build-up of carbon and debris fouling on metal and non-metal components of the firearm, and substantially reduces cleaning time, while providing increased protection against environmental components such as dust, dirt and rust. The gun oil composition can include a base oil having at least a high viscosity index, an oil having at least a medium viscosity index with a detergent additive, a low viscosity penetrating oil, and a sulfurized ester.

Hydrophilic coatings including a base coat layer and a top coat layer wherein at least one of the base coat and top coat compositions that form the hydrophilic coatings comprises a diacrylate compound have a number average molecular weight less than 1000.

A foam control agent and method of controlling foam for metal working fluids by use of a foam control agent, wherein the agent comprises at least a branched alcohol.

A lubricant composition for engines has at least one base oil and one fatty amine.
