Abstract:
A coating composition for imparting a hydrophobic film on a target surface is provided that includes an oil of a silicone oil or a fluoropolymer oil or a combination thereof, a resin, and a dry lubricant. A solvent is present to form a solution of the oil and resin. A coating is imparted to an applicator that in turn can transfer the coating as a hydrophobic film. The coating composition is stable and able to impart hydrophobic film even after storage for several weeks at elevated temperature. The coating composition does so through the exclusion of synthetic waxes especially including silicone waxes. A kit is also provided that includes a wiper blade having the above coating composition applied along with instructions for the securement of the wiper blade to a vehicle to impart the hydrophobic film to a vehicle windshield contacted by the wiper blade.

The lubricant is contained in the protective base material, and the protective base material is at least in part selectively removable. There is also provided a metal sheet or strip capable of forming, in particular of superplastic forming, and having a coating according to the invention at least partially on one or on both sides of the metal sheet and a method for manufacturing a metal sheet or strip according to the invention comprising the steps of providing a metal sheet or strip capable of forming, in particular of superplastic forming, and applying a coating according to the invention.
Abstract:
A method involves the coating of a metallic substrate with a blasting medium through sandblasting or equivalent techniques. The blasting medium is preferably a powder made of silicon nitride (or other ceramic or engineering materials). The sandblasting process allows the silicon nitride powder to form a loosely packed layer on the substrate. With additional treatment via rolling and/or sliding action against a secondary body in the presence of a liquid lubricant, the loosely packed particle layer turns into a flattened surface matrix consisting of particle clusters and irregular cavities. The silicon nitride particles are spontaneously attached to the substrate surface without the use of an adhesive agent which subsequently leads to the formation of a surface matrix exhibiting a chaotic hybrid topography with zero tensile stress when subjected to rolling/sliding contact pressure. This cluster-cavity matrix can evolve continuously (thus dynamic) and is immune to debris indentation from dirty lubricants. It is a complex, self organizing, and adaptive system. The practical value of this invention is to greatly enhance the fatigue and wear life of the bearing substrate and other objects coming into contact with the treated substrate.

The solid particles of the present invention include base particles and carbon fluoride particles attached to surfaces of the base particles.
Abstract:
Cutting fluids for brittle materials, e.g., silicon ingot, comprise, in weight percent: A. 70-99% polyalkylene glycol (PAG), e.g., polyethylene glycol; B. 0.01-10% PAG-grafted polycarboxylate; and C. 0-30% water. These cutting fluids are used with abrasive materials, e.g., silicon carbide (SiC), to form cutting slurries. The slurry is sprayed on the cutting tool, e.g., a wire saw, to cut a brittle work piece, e.g., a silicon ingot.
