Abstract

Described herein are coating systems for preparing multi-layered finishes, multi-layered finish coated substrates, and methods of applying multi-layered finishes to substrates. A coating system for preparing multi-layered finishes includes a base coating component and a clear coating component comprising effects particles. An additional coating system for preparing multi-layered finishes includes a base coating component, a printed coating component, and a clear coating component.

First claim

What is claimed is:

1. A multi-layered finish coated product, comprising:
an aluminum substrate comprising a 3xxx series aluminum alloy or a 5xxx series aluminum alloy, wherein the aluminum substrate comprises a beverage can end;
a base coating layer adhered to the aluminum substrate, wherein the base coating layer has a thickness of 0.1 μm to 15 μm; and
a clear coating layer comprising effects particles, wherein the clear coating layer is adhered to the base coating layer, and wherein the clear coating layer has a thickness of 1 μm to 20 μm.

2. The multi-layered finish coated product of claim 1 , wherein the effects particles comprise pearlescent particles.

3. The multi-layered finish coated product of claim 2 , wherein the pearlescent particles comprise flakes of mica.

4. The multi-layered finish coated product of claim 1 , wherein the beverage can end is a 200 can end, a 202 can end, a 206 can end, or a 209 can end.

5. The multi-layered finish coated product of claim 1 , wherein the base coating layer comprises a pigment or a dye.

6. The multi-layered finish coated product of claim 1 , wherein the base coating layer comprises a printed pattern.

7. The multi-layered finish coated product of claim 1 , wherein a concentration of the effects particles is from 0.1% to 20% by weight of a clear coating component of the clear coating layer.

8. The multi-layered finish coated product of claim 7 , wherein the concentration of the effects particles is from 0.5% to 10% by weight of the clear coating component of the clear coating layer.

9. The multi-layered finish coated product of claim 1 , wherein a coat weight of the clear coating layer is from 4.0 g/m 2 to 10.0 g/m 2 .

10. The multi-layered finish coated product of claim 1 , wherein a coat weight of the clear coating layer is from 5.0 g/m 2 to 8.0 g/m 2 .

11. The multi-layered finish coated product of claim 1 , wherein the clear coating layer comprises a wrinkled surface.

12. A multi-layered finish coated product, consisting essentially of:
an aluminum substrate comprising a 3xxx series aluminum alloy or a 5xxx series aluminum alloy, wherein the aluminum substrate comprises a beverage can end;
a base coating layer adhered to the aluminum substrate, wherein the base coating layer has a thickness of 0.1 μm to 15 μm; and
a clear coating layer comprising effects particles, wherein the clear coating layer is adhered to the base coating layer, and wherein the clear coating layer has a thickness of 1 μm to 20 μm.
