A substrate includes a metal component on a surface. A polymeric layer is deposited on the surface using molecular layer deposition. The polymeric layer includes a metalcone and has a thickness from 1 nm to 20 nm. The polymeric layer is stable at room temperature, but will undergo a structural change at high temperatures. The polymeric layer can be annealed to cause a structural change, which can occur during soldering.

The present disclosure is directed to processes, compositions and agents for inhibiting corrosion in various substrates, for example metal substrates. The present disclosure is also directed to corrosion inhibitors comprising organometallic polymers such as metal-organic frameworks (MOFs), including compositions and processes comprising MOFs for inhibiting corrosion in metal substrates.

The present invention relates to an eco-friendly and simple super-hydrophobic coating method that does not use harmful substances and special equipment. Coating according to the present invention may be performed as a single process without special equipment, and because only eco-friendly materials are used, the coating material may be easily used and discarded. In addition, even a three-dimensional pipe or a heat-exchanger having a complex shape may be modified to have super-hydrophobicity by applying the present coating, and a super-hydrophobic metal filter may be manufactured and used for oil-water separation. As a result, the present coating method is eco-friendly, simple, and applicable to various substrates, so it has great potential for application in various industries.

Coated articles, methods and coating compositions containing (a) a crosslinkable carboxyl-functional acrylic polymer made by polymerizing monomers including acidic monomer, multi-ethylenically unsaturated monomer and optional styrene or substituted styrene, and (b) a nitrogen-containing carboxyl-reactive crosslinking agent such as a beta-hydroxyalkylamide or beta-hydroxyalkylurea compound. The coating composition is useful in coating metal substrates including interior or exterior surfaces of food or beverage cans. The cured coating compositions can exhibit both good flexibility and high Tg.

Novel coatings disclosed herein can be used to mitigate dust adhesion. In one embodiment, a method of making a dust repellant coating includes combining a titanium dioxide sol with colloidal silica to form a mixture. The method also includes adding solvent to the mixture, stirring the mixture for about an hour, and filtering the mixture into a solution of titanium dioxide and silica dioxide.
