Method for covering elongated articles, in particular lines

A method of jacketing elongate items with an adhesive tape comprising a carrier in strip form that has been provided with a pressure-sensitive adhesive on at least one side, wherein the adhesive comprises a polymeric film former matrix and a curable composition, wherein the curable composition comprises one or more epoxy resins and at least one curing reagent for epoxy resins, wherein the curing reagent comprises at least one epoxy-amine adduct that is the reaction product of (A) at least one epoxy compound comprising a molecule having at least one cyclic ether group and (B) at least one amine compound, said at least one epoxy-amine adduct having a softening point of at least 100° C., said adhesive tape having a storability (Lf) as determined by dynamic differential calorimetry (DSC) of ≥0.82 after storage for 10 days at 60° C., said method comprising running the adhesive tape in a helical line around the elongate item or wrapping the elongate item by the adhesive tape in an axial direction, putting the elongate item together with the adhesive tape in a desired arrangement, holding the elongate item and the adhesive tape in this arrangement, and making the curable composition to cure by supplying thermal energy.
