Abstract
The invention relates to a method for surface coating a plane metal substrate, the method comprising the steps of: providing a coiled plane metal substrate; unwinding the coiled plane metal substrate; applying an adhesive layer onto a top surface of the plane metal substrate; and laminating a layered laminate comprising a PVC film and a PET film onto the top surface of the plane metal substrate, the PVC film contacting the adhesive layer, thereby forming a laminated assembly, wherein the plane metal substrate comprises austenitic stainless steel.

Method for surface coating a plane metal substrate, the method comprising the steps of:
- providing a coiled plane metal substrate;
- unwinding the coiled plane metal substrate;
- applying an adhesive layer onto a top surface of the plane metal substrate;
- and
- laminating a layered laminate comprising a PVC film and a PET film onto the top surface of the plane metal substrate, the PVC film contacting the adhesive layer, thereby forming a laminated assembly,
- wherein the plane metal substrate comprises austenitic stainless steel, wherein the layered laminate comprises amorphous PET coextruded with semicrystalline PET, optionally wherein the amorphous PET has been thermally fused with a rigid PVC film.
The method according to claim 1, wherein the PVC film comprises one or more pigments.
The method according to claim 1, wherein the adhesive layer is applied onto the plane metal substrate without application of an anticorrosive primer onto the top surface of the plane metal substrate.
The method according to claim 1, further comprising applying a strippable film covering the PET top layer.
The method according to claim 1, further comprising applying a backing coating to a bottom surface of the plane metal substrate.
The method according to claim 1, further comprising rewinding the laminated assembly resulting in a laminate coil.
The method according to claim 1, further comprising cutting the laminated assembly to produce slit coils.
The method according to claim 1, further comprising cutting the laminated assembly to produce pre-coated metal sheets.
A laminated assembly obtainable by the method of claim 1.
