Abstract: In one aspect, the present disclosure provides a polymer film with a low glass transition temperature. In one embodiment, when in contact with a metal substrate, the polymer film adheres to the metal substrate under heating and/or mechanical pressure. In one embodiment, the polymer film comprises a butadiene copolymer and a butylene polymer. In another aspect, the present disclosure further provides a method of masking a metal substrate using the polymer film. In yet another aspect, the present disclosure provides a method of chemically or electrochemically processing a metal substrate that is masked with the polymer film.
