Abstract:
The present invention provides a transition metal/polymer matrix composite material which has durable, wear and corrosion resistant and friction reducing characteristics which can be used in a powder or liquid form, or, which can be bonded to a desired surface at ambient temperature. The specific components are transition metal dichalcogenide (TMDs) disulfides of tungsten and molybdenum, and the polymer polytetrafuoroethylene (PTFE). This invention brings together the unique properties of organic chemistry (PTFE) and inorganic chemistry (TMD's) and creates a synergistic interaction optimizing the friction reducing properties of PTFE with similar friction reducing properties of select TMD's, and, the TMD's additional wear-resistance and natural tendency for forming a tenacious physical bond at a molecular level. The invention comprises a mixture of PTFE and TMDs (particularly tungsten disulfide and molybdenum disulfide) which can be applied to a substrate through a variety of mechanisms and manners to form a lubricious and wear-resistant layer ranging from 0.5 micron to 60 microns thick.
Abstract:
A combination of sulfur-free azoles, preferably benzotriazole and tolyltriazole, with sulfur-containing azoles, preferably 2-mercaptobenzothiazole or mercaptobenzimidazole, prevents discoloration, staining, or corrosion of metal surfaces being coated with an organic protective coating from aqueous dispersion or solution.
Abstract:
Thin impermeable, surface hardened, corrosion-resistant, durable, dry lubricant surface finishes are provided as well as surface finished products and methods for the production thereof. The surface finishes comprise particulate mixtures of sulfur containing metallic compounds and fluorocarbon polymers and are applied to surfaces of substrates such as metallic surfaces.
Abstract:
A surface-coated rubber or plastic sliding member having a coating with excellent durability and high slipperiness,wherein the coating comprises a solid lubricant such as molybdenum disulfide, a resin matrix and a reinforcement, said resin matrix comprising a fluoroolefin vinyl ether polymer resin and/or a fluoroolefin vinyl ether/vinyl ester copolymer resin.
Abstract:
In the cold drawing of steel tubing, an excellent lubrication which permits drawing the tubing while retaining its original metallic luster can be achieved by first contacting the surfaces of the tubing, both exterior and interior, with a colloidal titatium containing aqueous composition, drying the tubing, and then applying to the surface of the tubing a liquid lubricating composition comprising (i) from 40 to 95 % of a first component selected from the group consisting of olefin/oil or olefin/fat compounds which contain from 23 to 30 % of sulfur and olefin/higher ester compounds which contain from 23 to 30 % sulfur, including mixtures of two or more chemical species meeting this description; and (ii) from 5 to 50 % of a second component selected from the group consisting of oil soluble polymer compounds, fats and oils, synthetic oils, mineral oils, higher fatty acids, and the amine salts of higher fatty acids.
Abstract:
Contact of acid or alkaline cleaned aluminum surfaces, particularly cans, with a water based composition containing a combination of (i) alkoxylated phosphate esters, (ii) ions of aluminum, zirconium, iron, tin, and/or cerium, (iii) a metal etching component, and (iv) a combination of alkoxylated alcohol and alkoxylated alkyl phenol emulsifiers, gives the surface after drying lowered surface friction without loss of high quality printability and lacquer adhesion and removes any brown spotting on the cans that may have developed during the cleaning or post-cleaning rinses. The cans after treatment are substantially free from any water breaks when rinsed with water. The foaming resistance and storage stability of the water based composition as described above, and of other similar surface friction reducing treatments for aluminum containers, may be advantageously increased by adding a biocidal agent, preferably hydrogen peroxide, and a combination of liquid paraffin, solid wax, and a high molecular weight fatty acid derivative(s) as antifoam agent.
