Idea: Coating of metallic surfaces with silica-glass for corrosion

protection

SiO2 offers excellent chemical stability in both acidic and alkaline

environments

New experimental processes outperform previous results Applicable to a variety of Al alloys

The yellow tone is an artifact from the chromium oxide formed during the curing process.The red/green colour nuances is an optical phenomenon rising from variations in coating thickness

On Aluminium there are no colour toning of the coating.Due to the more rough substrate surface, the read/green nuances is not seen because of the scattering of the incident light.
