Protective coatings, for metals

Dr. Hui has worked on various projects, including chemical sensors, solid oxide fuel cells, magnetic materials, gas separation membranes, nanostruc-tured materials, thin film fabrication, and protective coatings for metals. He has more than 80 research publications, one worldwide patent, and one U.S. patent (pending). He is currently leading and involved in several projects for the development of metal-supported solid oxide fuel cells (SOFCs), ceramic nanomaterials as catalyst supports for high-temperature PEM fuel cells, protective ceramic coatings on metallic substrates, ceramic electrode materials for batteries, and ceramic proton conductors. Dr. Hui is also an active member of the Electrochemical Society and the American Ceramic Society. 

While other organic esters are commercially available, namely cellulose butyrate and cellulose propionate, by far the most widely used is cellulose acetate, which is available as plastics, in films, sheets, fibers, and lacquers. Cellulose acetate is used in the manufacture of display packaging and as extruded film for decorative signs, and to coat a variety of fibers. Injected molded products include toothbrush handles, combs, and brushes. It is also used in lacquers and protective coatings for metal, glass, and paper. Cellulose acetate films are used in reverse osmosis to purify blood, fruit juices, and brackish water. Some eyeglass frames are... 

The unsaponifiables of woolwax, known as woolwax alcohols, are in considerable demand by cosmetic and pharmaceutical industries. Woolwax has a great affinity for water, of which it will absorb 25 to 30%. Refined woolwax is kneaded with water to produce a water-white, colorless oiiilmenL, known as hydrous lanolin or lanolin USP. Anhydrous lanolin is widely used in cosmetic creams, since it is readily absorbed by the skin. It is also used m leather dressings and shoe pastes, as a superfatting agent for toilet soap, as a protective coating for metals, etc. United States consumption of wool wax is about 1.5 million lb/year. 

Other industries developed in the same manner the use of ozone for the treatment of surfaces. Hoechst AG claimed a process of ozonization of poly(ethylene-co-5-vinyl-2 norbornene) to give polymers usable as protective coatings for metals or plastic materials [211].

The bitumen obtained is the unmodified native bitumen with a substantial percentage of high melting, aliphatic soluble components. These are separated from the low melting components by solvent extraction or solvent precipitation. The high melting components are utilized in protective coatings for metals or in heat resistant road surface compositions. 

Uses.—Metallic chromium is used industrially in the manufacture of certain varieties of steel. It enters into the composition also of many non-ferrous alloys (see p. 17), the importance of which is increasing. It may be used as a protective coating for metals, either in the form of chromium plate (see p. 10), or by causing the metal to diffuse into other metals at temperatures below their melting-points ... 

Use Chemical polishing agent, protective coatings for metal surfaces, catalyst. 

Use Metal cleaners, electrolytic or chemical polishing agents for the formation of protective coatings for metal surfaces, and as a catalyst. 

Some other major uses, by types, are as follows Solvent cutback and water emulsion, nonfibrated coatings are used as protective coatings for metal and masonry. Solvent cutback and water emulsion, fibrated coatings are used in roofing, waterproofing, and industrial insulation, and in automobiles for protection and sound deadening.

Products and Uses Considered a protective coating for metal. Found in polishes for vehicle surfaces and metal protectors. 

These can be either (a) common film structures (which can be either in the common monolayer or in series of multilayered-coextruded film types) or, (b) hybrids (hybrid structures can be of plastic-to-metal or plastic-to-paper type, i.e., multilayer films with paper and with metal foils, protective coating for metals, and so on).
