Patent ID: 8709200

Claim:
A method for corrosion control treatment of metal surfaces, the method comprises: applying an adhesive tape to a metal surface, wherein the adhesive tape has a layer comprising an olefin polymer having a density of between 0.86 g/cm 3 and 0.91 g/cm 3 and a crystallite melting point of at least 105° C., wherein the olefin polymer comprises ethylene or propylene and at least one further comonomer selected from C 2 to C 10 olefins, and a tackifier resin having a polydispersity of less than 2.1 and present at a concentration of at least 50 parts by weight per 100 parts by weight of the olefin polymer; and heating the adhesive tape such that the layer melts to form a corrosion control layer on the metal surface.
