Disclosed is a method of sealing an anodization layer including contacting the anodization layer with a solution at a temperature greater than freezing and less than 160° F. wherein the solution comprises graphene particles and a corrosion inhibitor.

Sealed anodization layer

In one aspect, a spray foam chemical conversion coating includes a non-hexavalent chromium aqueous chemical conversion coating solution, a foaming agent, and a propellant. In another aspect, a method of producing a corrosion-resistant coating includes spraying a foam chemical conversion coating on a surface of a metal substrate, allowing the foam chemical conversion coating to react with the surface, and removing excess foam chemical conversion coating from the surface. The foam chemical conversion coating contains no hexavalent chromium.

Application of type II chemical conversion coatings (CCCS) using foaming agents

A handheld applicator for delivery of post-treatment coating following application of a conversion coating includes a first vessel extending longitudinally and containing SOCOSURF PACS™ solution, a second vessel extending longitudinally and containing hydrogen peroxide, a pH indicator contained in one of the first or second vessels, a mixing region configured to combine the SOCOSURF PACS™ solution, hydrogen peroxide, and pH indicator.
