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.

No-rinse pretreatment methods and compositions

There is provided a trisiloxane having a 3-(meth)acryloxy-substituted (hydroxylcyclohexyl)ethyl group, useful in making water absorbing silicone-hydrogel films for biomedical devices, such as contact lens, and a process for producing these monomers. This invention also provides for copolymers made from the trisiloxane having a 3-(meth)acryloxy-substituted (hydroxylcyclohexyl)ethyl group described herein.

(Meth)acryloxy-containing trisiloxane, siloxane-containing polymers and biomedical devices therefrom

There is provided new mono-(meth)acrylate functionalized hydrophilic silicone monomers containing a polyether with branched linking group, useful in making water absorbing silicone-hydrogel films for contact lens applications. This invention also provides homo-polymers and copolymers made from the mono-(meth)acrylate functionalized hydrophilic silicone monomers described herein. Also provided is a process for producing the monomers and polymers described herein and contact lenses produced from the same.

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.

Storage stable composition of partial and/or complete condensate of hydrolyzable organofunctional silane

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.

Hydroxyl-functional carbamoyl organosilicon compounds of low VOC and HAP generating potential, anti-corrosion and/or adhesion promoting coating composition containing same, environmentally benign method of coating metal therewith and resulting coated metal

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.

Epoxysilanes, processes for their manufacture and curable compositions containing same

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.
