Coated pipe comprising polyolefin layer with enhanced adhesion

摘要

The present invention relates to a structure comprising
(i) a layer or profile (A) composed of a first material, and
(ii) a polyolefin layer or profile (B) adjacent to layer or profile (A) which is composed of a composition comprising a base resin comprising a polyolefin,
characterized in that the surface of any or both of layer or profile (A) and layer or profile (B) has/have been treated with a composition comprising an organosilicon compound before (A) and (B) are brought adjacent to each other, to a process for the production of such a structure, to an article, in particular a coated pipe, comprising such a structure and to the use of a composition comprising an organosilicon compound as an adhesion promoter in such a structure.
