Abstract
A polymer based coating for application to rolled stock, such as aluminum is provided. A device for applying the polymer based coatings is also provided. Polymer based coatings applied to rolled stock, such as aluminum, are advantageous compared to anodized coatings since the polymers are self-leveling and may be applied to lower grades of aluminum, while still providing a smooth and durable surface finish.
Claims9
A process for coating rolled material substrate, said process comprising:
- unrolling the rolled material stock of aluminum or an aluminum alloy to expose a metal surface having native oxides thereon;
- pre-cleaning the rolled material substrate with a solvent that retains the native oxides;
- applying a polymeric coating formulation directly onto the native oxides on the metal surface after pre-cleaning the rolled material substrate with the solvent;
- and
- hardening said polymeric coating formulation into a coating on the native oxides the rolled stock substrate, said coating having a reflectivity of greater than 95% and withstanding a Tide test for over 8 hours at 40° C. with no compromise relative to as-formed surface reflectivity.
