METHOD FOR PRODUCING elongated tubular devices with systems of anticorrosion coating with self-healing

摘要

The present invention A process for providing an extended tubular article or one or more sections of the extended tubular article with a corrosion protecting system, wherein (a) a layer of an adhesive composition is applied to the surface of the extended tubular article or the one or more sections of the extended tubular article, and (b) a corrosion protecting layer is applied to the layer of the adhesive composition, the adhesive composition comprising a polyolefin blend, wherein the polyolefin blend comprises 30 % to 100 % by weight of a polyisobutene and 0 % to 70 % by weight of an olefin polymer, based on the total weight of the polyolefin blend, wherein said polyisobutene is has a glass transition temperature of lower than -400C and a number average molecular weight Mn of 1300 to 1.000.000.
