Abstract: A process is provided for inhibiting the corrosion of metal that comes into contact with a static or flowing aqueous medium which comprises contacting at least a portion of the exposed surface of the metal with aqueous medium containing a metal corrosion inhibiting amount of at least one ureido silane and, optionally, one or more added inorganic and/or other organic materials.

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: 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: A method of coating at least a portion of the exposed surface of a metal comprises: a) applying to said surface a curable coating composition comprising an aqueous solution of at least one partially or substantially completely hydrolyzed, and optionally partially condensed, silane possessing one or more hydroxyl groups and, optionally, one or more organonitrogen groups, said hydroxyl group(s) and optional organonitrogen group(s) being bonded to different carbon atoms of a bridging group linking such group(s) to the silicon atom of the partially or substantially completely hydrolyzed and optionally partially condensed silane; and, b) curing the curable coating composition on the surface of the metal to provide an anti-corrosion and/or adhesion promoting coating thereon.

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: Disclosed are curable compositions based on a curable polymeric component containing hydrolyzable alkoxysilyl groups and also containing an oligomeric component which is composed at least in part of units containing hydrolyzable alkoxysilyl groups. The oligomeric component serves both to lower the viscosity of the composition, and to react with the polymeric component during cure, thereby lessening the use of volatile solvents.

Abstract: This invention provides a process for making a silylorganocarbamate or a silylisocyanurate which process comprises reacting an aminosilane with a dialkyl carbonate, diaryl carbonate or a mixture thereof in the presence of a basic catalyst to obtain the silylorganocarbamate; optionally, neutralizing the basic catalyst and residual aminosilane with a neutralizing agent; and adding a cracking catalyst and heating at subatmospheric pressure to obtain the silylisocyanurate; or heating a silylorganocarbamate at a temperature sufficient for dissociation of the carbamate at subatmospheric pressure in the presence of a cracking catalyst and a timerization catalyst to obtain a silylisocyanurate.

Abstract: Silylated polyester resins comprising the acid salt of a Michael addition adduct of an aminoorganosilane and a conjugated unsaturated polyester resin containing a polyethylene oxide chain segment useful for sizing glass fiber reinforcement of polyester molding composites.
