BONDABLY COATED METALLIC MEMBER

摘要

The present provides a bondably coated metallic member comprising a metallic member having a low surface energy polymeric coating, said low surface energy polymeric coating having been surface activated on at least a portion thereof, and having on said surface-activated portion a bondable high surface energy polymeric coating. The present invention also provides a bondably-coated metallic pipe comprising metallic pipe having a low surface energy mainline polymeric coating thereon extending over the pipe except at a bare zone adjacent each end of the pipe that is free from said main-line coating; a portion of said mainline coating adjacent each bare zone having been surface activated and having on said surface activated portion a bondable high surface energy polymeric coating.
