Abstract

A method for applying a coating to a surface of an aircraft including applying a basecoat layer, applying an ink layer onto a top surface of the basecoat layer, and applying a topcoat layer onto a top surface of the ink layer where each of the basecoat layer, the ink layer, and the topcoat layer interact to form a single homogenous layer with respect to a film forming component on the surface of the aircraft.

Claims (19)

1 . A method for applying a coating to a surface of an aircraft, the method comprising:

(a) applying a basecoat layer;

(b) applying an ink layer onto a top surface of the basecoat layer; and

(c) applying a topcoat layer onto a top surface of the ink layer,

wherein:

each of the basecoat layer, the ink layer, and the topcoat layer interact to form a single homogenous layer with respect to a film forming component on the surface of the aircraft; and

each of the basecoat layer, the ink layer, and the topcoat layer share a first reactant, the basecoat layer and the topcoat layer share a second reactant, and the first reactant and the second reactant interact to form the film forming component.

2 . The method of claim 1 , wherein the formation of the single homogenous layer is based upon the chemical compatibility of the basecoat layer, the ink layer, and the topcoat layer.

3 . The method of claim 1 , wherein the first reactant is an alcohol containing compound and the second reactant is a isocyanate containing compound.

4 . The method of claim 1 , wherein the first reactant comprises one of a polyester-based compound, an acrylic-based compound, a polycarbonate-based compound, and/or a polyether-based compound.

5 . The method of claim 1 , wherein any one of the basecoat layer, ink layer, and the topcoat layer are dissolvable in a solvent.

6 . The method of claim 1 , wherein the single homogenous layer substantially maintains the physical and chemical characteristics of the basecoat layer and the topcoat layer.

7 . The method of claim 6 , wherein the maintained physical and chemical characteristics includes any one of a chemical resistance, a resistance to erosion, a durability, a smoothness, a surface adhesion, an intercoat adhesion, an intracoat adhesion, a buffability, and/or a stain resistance of either the basecoat layer and/or the topcoat layer.

8 . The method of claim 1 , wherein the basecoat layer is applied in a first spraying operation.

9 . The method of claim 1 , wherein the ink layer is applied by a first printing operation.

10 . The method of claim 9 , wherein the printing operation is inkjet-type printing.

11 . The method of claim 9 , wherein the topcoat is applied in a second spraying operation.

12 . The method of claim 11 , wherein the first spraying operation and/or the second spraying operation are performed manually or robotically.

13 . The method of claim 1 , wherein the basecoat layer is applied on an exterior surface of the aircraft.
