Room temperature curable functionalized HNBR coating

A method for coating an elastomer substrate, comprising:

• applying a coating composition to an elastomeric substrate, said coating comprising a solvent, a functionalized hydrogenated copolymer comprising i) at least one repeating unit derived from a conjugated diene monomer, ii) a non-conjugated ethylenically unsaturated monomer unit derived from one or more ethylenically unsaturated monomers of an unsaturated nitrile or monovinyl aromatic hydrocarbon, and iii) an active hydrogen-containing, or ethylenic unsaturated, or hydrolyzable functional group-containing monomer, or graft-linked compound, or combinations thereof, wherein said functionalized hydrogenated copolymer has an unsaturation level between about 0.1 and 20 mole percent, and wherein said coating contains a curing component reactive with at least the iii) active hydrogen-containing, or ethylenic unsaturated, or hydrolyzable functional group-containing monomer, or graft-linked compound, or combinations thereof comprising at least one group selected from an isocyanate group, blocked isocyanate group, isocyanatosilane, amine, silyl ether, silyl chloride, and a carbodiimide group, or a combination thereof, and
• curing the coating composition by allowing said coating to dry at either ambient or elevated conditions or a combination thereof.
