  • Silicate treatment for coated substrate
    Patent number: 4365003
    Abstract: 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.

  • Concentrate for liquid coating composition for metal substrates
    Patent number: 3940280
    Abstract: A coating composition is prepared, typically, from a liquid composition precursor component to which there is added a concentrate adapted for blending with such precursor component. The concentrate contains pulverulent metal and a very minor amount of water-soluble cellulose ether, while preferably further containing water-dispersible organic liquid. The precursor component is exemplified by a solution of an inorganic acid such as chromic acid in water.
