Composite materials having a coated edge and methods thereof
View Patent ↗Disclosed herein are articles having an edge that is partially, or entirely sealed with one or more coatings including a polymeric material. The article may include a coating selected so that one surface (e.g., a face surface) has a desired property (e.g., an appearance, such as a chrome appearance), and a second surface (e.g., a different face surface, or an edge surface) is covered with a different material, where the different coatings provide protection to at least the edge surface. Also disclosed are coating materials including a tracer component. Also disclosed are methods for coating a substrate. Also disclosed are methods for confirming the presence of a coating, particularly on an edge surface.
1. A method of forming a coated article comprising the steps of:
i) providing a bare article having a first metallic face surface and an opposing second metallic face surface, and having an edge surface;
ii) covering the first metallic face surface with a layer of an anti-corrosion polymeric material;
iii) plating the second metallic face surface with one or more metallic plating layers to form a plated article having a plated surface, wherein the plated article has a bare surface between the plated surface and the surface coated with the anti-corrosion polymeric material, wherein the bare surface is generally free of the anti-corrosion polymeric material and is either free of the one or more metallic plating layers or includes only partial plating;
iv) coating the bare surface with one or more polymeric coatings.
2. The method of claim 1 , wherein the bare article is a monolithic metal article.
3. The method of claim 1 , wherein the bare article includes a composite including metal layers and a polymeric core layer having metal particles and/or metal fibers, wherein the edge surface includes an edge surface of the metal layers and an edge surface of the polymeric core layer.
4. The method of claim 3 , wherein the bare surface includes at least a portion of an edge of the composite including the polymeric core layer.
5. The method of claim 3 , wherein the polymeric core layer includes a non-polar polymer and the polymeric coating includes a polar polymer.
6. The method of claim 3 , wherein the polymeric core layer includes a sufficient amount of the metal fiber and/or metal particles for partial adhesion of the plating to the edge surface of the polymeric core layer.
7. The method of claim 3 , wherein the step of covering the first metallic face surface is before the step of plating the second metallic face surface.
8. The method of claim 1 , wherein a thickness of the layer of the anti-corrosion polymeric material is about 1 mm or less.
9. The method of claim 1 , wherein substantially all of the surfaces of the bare article are covered by any combination of the anti-corrosion polymeric material, the metallic plating layer, or the polymeric coating.
10. The method of claim 9 , wherein a first metallic layer of the one or more metallic plating layers has a thickness less than a thickness of a second metallic layer of the one or more metallic plating layers.
11. The method of claim 1 , where the one or more metallic plating layers includes a chrome plating layer; and the one or more polymeric coatings includes a primer material.
12. A coated article prepared by the method of claim 1 .
13. A method comprising the step of
i) covering a first face surface of a composite material with a layer of an anti-corrosion polymeric material; wherein the composite material includes a first metal layer, a second metal layer, and a polymeric core layer between the first and second metal layers, wherein the polymeric core layer includes a non-polar polymer, and metal particles and/or metal fibers, wherein the composite material includes the first face surface, an opposing second face surface, and an edge surface of the polymeric core layer;
ii) plating at least the second face surface of the composite material with one or more metal containing plating layers;
iii) coating the edge surface of the polymeric core layer with a polymeric coating including a polar polymer.
14. The method of claim 13 , wherein the edge surface of the polymeric core layer is at least partially coated by the plating layer(s).
15. The method of claim 14 , wherein the polymeric core layer includes a sufficient amount of the metallic fibers and/or the metallic particles so that the plating layer(s) at least partially adheres directly to an edge surface of the polymeric core layer.
16. The method of claim 15 , wherein the composite material is entirely encased by a combination of the anti-corrosion polymeric coating layer, the polymeric coating, and the plating layer(s).
17. The method of claim 14 , wherein a first metallic layer of the one or more metal containing plating layers has a thickness less than a thickness of a second metallic layer of the one or more metal containing plating layers.
18. The method of claim 1 , wherein the polymeric coating includes a tracer compound and the method includes detecting the tracer compound to confirm the presence of the polymeric coating.
19. The method of claim 13 , wherein the polymeric coating includes a tracer compound and the method includes detecting the tracer compound to confirm a presence of the polymeric coating.
20. A coated article prepared by the method of claim 13 .
