Abstract
A method provides an adhesive strip to protect metal surfaces from corrosion. The adhesive strip has a layer of olefin polymer with a density between 0.86 g/cm3 and 0.91 g/cm3 and a crystallite melting point of at least 105° C. The adhesive strip is applied onto a metal surface, and the strip is heated such that the layer is molten, thereby forming a corrosion protection layer for the metal surface.
Claims19
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/cm3 and 0.91 g/cm3 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 C2 to C10 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.
