摘要： A thermoplastic resin-coated metal sheet obtained by coating at least one surface of a metal sheet with a thermoplastic resin via a polyester type primer, wherein the polyester type primer, if it is in the form of a 10 µ m-thick dry primer sheet, has a breaking elongation in a range of 9 to 200% at a tension speed of 1000 mm/min. and an MEK extractability in a range of 3 to 40%. Without using a special thermoplastic resin-coated film or surface-treated metal sheet, therefore, the cans and can lids can be formed using the thermoplastic resin-coated metal sheet of the invention maintaining excellent and close adhesion during the working, preventing the can body from breaking and the thermoplastic resin coating from peeling at the flange-forming portion during the working, the cans and can lids excelling in dent resistance and economy.

摘要： An alkoxysilane is contacted with water and an inorganic acid to form a first composition. A zirconium alkoxide is contacted with an organic acid to form a second composition. One or more alkoxysilanes and an organic acid are contacted with a mixture of the first and second compositions to form a sol-gel composition, to which a photoinitiator is added. The sol-gel composition has a ratio of a number of moles of silicon to a number of moles of zirconium (n Si /n Zr ) ranging from about 2 to about 10. The sol-gel composition is applied on a substrate (e.g., an aluminum alloy substrate) multiple times to form multiple sol-gel layers, and at least one of the sol-gel layers is cured by UV radiation. The multiple sol-gel layers are then thermally cured.

摘要： A method for forming a protective coat upon an article includes forming a liquid coating mixture comprising a cross-linking agent and a polymer dissolved within a solvent; applying a first coat of the coating mixture upon the article; evaporating the solvent from the first coat; and cross-linking the article. Also disclosed is a device containing an exterior surface at least partially covered by a coating comprising a cross-linked polymer and a filler material that is selected from the group consisting of a fullerene, a micro-encapsulated material, and a combination of two or more thereof.

摘要： A method to prevent corrosion of a susceptible article of a two-article system, in which first and second articles of the two-article system have surfaces facing one another and in which the two articles have different anodic indices includes applying a coating material to the surface of the first article and curing the coating material on the surface of the first article. The method further includes contacting and securing the surface of the first article with the surface of the second article. The two articles exhibit substantially no corrosion following exposure to a corrosive environment under standard GMW 17026 for a 15 year simulated test.
