Abstract: This invention pertains to the protection of metals from corrosion and/or fouling from exposure to environments such as, for example, seawater. The protection in accordance with this invention is achieved through the use of conductive zinc-containing coatings in combination with applied current cathodic protection.

Abstract: The invention is directed to a process for making a reactive silane oligomer having low polydispersity, viscosity and volatility. The process utilizes reacting unsymmetrical difunctional silane monomers with water, diol monomers, or a combination thereof to make the reactive silane oligomer. The unsymmetrical difunctional silane monomers are with silane reactive groups having significantly different reactivities. Use of such reactive silane oligomers results in multi-component coating compositions having high miscibility, low VOC, low viscosity and high percentage of solids.

Abstract: This invention concerns a process for imparting corrosion and creep resistance to a coating prepared from a particulate polymer composition and applied from a fluidized bed or by electrostatic spraying over metal substrates. The process of the present invention provides for maintaining the content of acid functionality of an acid-functionalized semicrystalline or acid-functionalized amorphous particulate polymer of the particulate polymer composition within a desired range. The acid functionality on the particulate polymer can be maintained, by crosslinking and/or neutralizing, within a desired range of the acid content which results in imparting corrosion and creep resistance to the coating applied over the metal substrates. Neutralizing the acid functionality of the polymer component results in hardening the coatings resulting therefrom. The process further provides for adding anticorrosive pigments to the composition for further improving corrosion resistance of the resultant coatings.

Abstract: Automotive emblem lighting assemblies, and methods of making. One embodiment comprises a bezel mounted to a transparent/translucent lens, with junction therebetween which can be sealed. Viscous curable material is dispensed upon the lens rear and bezel. Bubbles within the viscous material are removed. A housing is bonded with the viscous material and bezel/lens. The curable material is cured and seals the assembly. A light source shines through the lens. The lens can have an emblem shaped recess or recesses. Part of the lens rear can be coated with substantially opaque material. A reflective-transmissive material coats at least part of the lens rear for light transmission/reflection. Diffusion can be by a diffusing agent in the viscous material, reflective surface on the light source, or diffusing material on the lens.Modifications: lens with no substantially opaque coating, an emblem shaped lens, reflective-transmissive material on the lens rear, and no bezel.

Abstract: An improved process for preparing a vinyl-substituted dioxo compound, in which process a vinyl aldehyde is reacted with a compound having three or more hydroxyl groups. In particular, the reaction is carried out, using an acid catalyst, in an organic solvent comprising an aliphatic solvent which forms a binary azeotrope with water as the reaction is driven to completion.
