Patent ID: 7323076

Claim:
A method of forming an assembly comprising a substrate, a first layer, a second layer and a fluorocarbon film, the method comprising: forming the first layer on a first surface of the substrate wherein the first surface is an exterior-facing surface and has a texture, wherein the first layer is an adhesive mixture that includes a reactive isocyanate compound and a catalyst that catalyzes a reaction between the isocyanate compound and hydroxyl functional groups on the surface of the substrate and the substrate is a fiber reinforced cement material; forming a second layer on a second surface of the substrate wherein the second surface extends substantially perpendicularly from lateral edges of the first surface of the substrate and the second layer is an adhesive mixture; placing a fluorohydrocarbon film on the first surface of the substrate; and applying heat and pressure to the film in a manner such that the film is bonded to the first surface and second surface of the substrate at the same time, wherein the texture of the first surface is transferred through the film.
