CA 2284055

The present invention relates to coated metal substrates such as metal piping having improved environmental stress crack resistance and resistance to hydrolytic and/or cathodic disbondment. The coating composition contains a blend of modified and unmodified polyolefins as well as a tackifier. For cathodic disbondment resistance, the preferred tackifiers are rosin esters or hydrogenated versions thereof. The modified polyolefins are grafted versions of metallocene or non-metallocene produced low density or high density polyethylenes.

Cette invention concerne des substrats métalliques enrobés, tels que des canalisations métalliques, qui possèdent une meilleure résistance à la fissuration due aux contraintes de l'environnement, ainsi qu'une meilleure résistance au décollement hydrolytique et/ou cathodique. La composition de revêtement comprend un mélange de polyoléfines modifiées et non modifiées ainsi qu'un agent collant. Afin d'assurer la résistance au décollement cathodique, les agents collants préférés consistent en des esters de rosine ou en des versions hydrogénées de ces derniers. Les polyoléfines modifiées consistent en des versions greffées de polyéthylènes de haute ou de faible densité produits ou non à l'aide de métallocènes.
