Abstract: Conversion and passivation coatings and methods for metal surfaces such as steel and aluminum are disclosed. The coating compositions comprise an aqueous sol of cerium oxide and/or silica particles and a ureido silane compound. The methods of the invention comprise contacting the requisite metal surface with the coating composition.

Abstract: Conversion and passivation coatings and methods for treating metal surfaces such as steel and aluminum are disclosed. The coating compositions comprise a silane and a stabilizing agent. The methods herein comprise contacting the requisite metal surface with the coating composition.

Abstract: There is provided a hydroxyl-functional carbamoyl organosilicon compound, an anti-corrosion and/or adhesion promoting coating composition based thereon, a method for coating a metal surface employing the coating composition and the resulting coated metal article.

Abstract: Disclosed herein is an article or device such as surgical devices, needles such as surgical needles, razors, cutting/slicing devices containing a metallic surface, a primer layer disposed on the metallic surface, and a top coat disposed on the primer layer, wherein the primer layer is formed from a primer composition containing a silanol-containing organopolysiloxane resin and a crosslinking agent selected from the group consisting of alkyl silicates, boric acid, borates, acetoxysilanes, ketoximesilanes, and combinations thereof, and wherein the top coat is formed from a top coat composition containing an alkenyl functional polyorganosiloxane, an organohydrogensiloxane, and a hydrosilylation catalyst.

Abstract: Epoxysilanes are provided which contain at least one epoxy group, at least one hydrolyzable silyl group and one or more linkages containing a carbonyl group bonded to heteroatoms selected from the group consisting of oxygen, sulfur and nitrogen with at least one such heteroatom being nitrogen, there being no such linkage in which both an epoxy group and hydrolyzable silyl group are directly or indirectly bonded to the same nitrogen heteroatom in the linkage.

Abstract: A coating composition is provided which includes an adhesion promoter or a crosslinker silane which, upon hydrolysis, of its hydrolyzable sites, produces a reduced amount of volatile organic compound compared to that produced by the hydrolysis of a silane possessing an equivalent number of hydrolyzable sites all of which are hydrolyzable alkoxy groups.

Abstract: There is provided a hydroxyl-functional carbamoyl organosilicon compound, an anti-corrosion and/or adhesion promoting coating composition based thereon, a method for coating a metal surface employing the coating composition and the resulting coated metal article.
