Vehicle sheet coating

Abstract

A multilayer vehicle exterior coating is both durable and easy to install and conforms FAA standards. This vehicle sheet coating has no film or substrate resulting in a finished coating sheet that is about 6 mils thick (0.006″). The multilayer protective sheet material is suitable for application to vehicle exterior surface.

Claims

1. A method of forming a 0.006″ thick sheet coating for airplanes comprising the steps: depositing a 0.002″ thick adhesive layer on a removable backing leaving a top surface exposed; preparing the top surface of the adhesive layer with a treatment solution; testing the top surface to confirm that the adhesive layer is ready for the application of a color layer; applying one or more color elements to the top surface of the adhesive layer to form a color layer; and applying clearcoat with translucent pigment to the color layer to form a modified clearcoat layer on the color layer with the color layer between the modified clearcoat layer and the adhesive layer, the translucent pigment operable to form a dull finish on the modified clearcoat layer.

2. The airplane sheet coating of claim 1 wherein the treatment solution is selected from the group consisting of alcohol, methyl ethyl ketone or a combination of alcohol and methyl ethyl ketone.

3. The airplane sheet coating of claim 1 wherein the step of testing the top surface is followed by the step of: reapplying the treatment solution to the top surface; retesting the top surface to confirm that the adhesive layer is ready for the application of a color layer.

DETAILED DESCRIPTION OF THE INVENTIONS

(3) FIG. 1 is an exploded perspective view of the layers of vehicle sheet coating 1. FIG. 2 is an exploded side view of the vehicle sheet coating 1 with a conventional clearcoat layer 3. Vehicle sheet coating 1 is formed of three layers, adhesive layer 4, color layer 5 and modified clear coat layer 6. Adhesive layer 4 is generally about 2 mils thick (0.002″) and may be any suitable adhesive with a top surface 4T that has been treated with a treatment solution to make the adhesive layer receptive to the application of color. The treatment solution may be methyl ethyl ketone (MEK) and/or alcohol. Color layer 5 is composed of any suitable color elements including toner, ink or solvent ink. Modified clearcoat layer 6 is formed, contrary to the clearcoat manufacturers instructions for use, by adding translucent pigment to the clearcoat. The added pigments enable the modified clearcoat layer to better adhere to the color layer and to dry with a dull/cloudy finish on top surface 6T. The dull/cloudy finish enables a painter applying a conventional clearcoat layer such as layer 3 to a vehicle with a vehicle sheet coating 1 on its surface to distinguish which areas of the surface/vehicle sheet coating have been covered with conventions clearcoat as the conventional clearcoat layer 3 will be smooth and shiny.

(4) To produce vehicle sheet coating 1, the adhesive layer 4 is formed on any suitable removable backing such as backing 7. The top surface 4T of the adhesive layer 4 is prepared by wiping the surface with either MEK or alcohol or a mixture of MEK and alcohol. The chemicals clean and soften the adhesive surface, which makes it more ink receptive. Most of the time alcohol works fine, but on a colder day or when the humidity is low, MEK is required. We do a scratch test to see if the material is soft enough to accept the ink. Alternatively the alcohol and MEK may be applied together until the adhesive softens sufficiently to accept the application of the color layer. Color layer 5 is applied to the prepared top surface 4T. Once the color layer 5 is applied to the adhesive, the application of the modified clearcoat layer 6 to the top surface 5T must be completed within about 12 to 24 hours depending the ambient temperature and humidity. Higher temperatures shorten the time during which the modified clearcoat layer may be successfully applied. The modified clearcoat layer 6 is then deposited on to color layer 5 forming a dull/cloudy top surface 6T that will be receptive to conventional clearcoat after the vehicle sheet coating is applied to the desired vehicle.

(5) The process of forming vehicle sheet coating 1 may also be performed in reverse of the process outlined above. The modified clearcoat layer may be applied to a suitable removable substrate and then the color layer may be applied to the modified clearcoat layer and the adhesive may be applied over the color layer.

(6) Once formed, one or more vehicle sheet coatings may be attached to a vehicle such as an airplane by removing the backing 7 from the adhesive layer and pressing the vehicle sheet coatings in place. When the vehicle sheet coatings are applied to the vehicle, a conventional clearcoat 3 is applied over the vehicle sheet coatings.
