<p>SILICATE TREATMENT FOR COATED SUBSTRATE Metals, particularly ferrous metals, coated for corrosion resistance with coatings containing particulate metal and hexavalent chromium-providing substance can now be made further corrosion resistant, as well as heat resistant, with a topcoat of silica substance. In addition, mar resistance plus improved outdoor weathering is also achieved, without sacrifice to other characteristics,e.g., coating adhesion.</p> |
