Patent number: 8753719
Abstract: Methods for treating various substrates to impart unique and artistic finishes thereto, comprising the application of a plurality of separate pigmented curable liquid compositions thereto. In some embodiments the pigmented curable liquid compositions are applied in such fashion to preclude formation of a homogeneous pigmented mixture. In some embodiments this is achieved by applying a second pigmented curable liquid composition over a first pigmented curable liquid composition prior to the full cure of the former. In other embodiments, this is achieved by simultaneous application of two pigmented curable liquid compositions which are non-homogeneous.

The precursor may preferably be a CeO2 (NO3) based sol with preferably 20% CeO2 having a particle size of 10-20 nm and a pH of 1.5. Further the pigment may be a manganese ferrite black spinel, Mn3Cu2FeO8.

Patent number: 8383204
Abstract: A method of applying to a clean metal surface an aqueous solution comprised of a small percentage of organofunctional siloxane oligomers. The organofunctional siloxane oligomers used in this method include silsesquioxanes. The organofunctional siloxane oligomers are applied to a metal surface prior to the application of a topcoat and function to inhibit corrosion of the metal surface.

Abstract: Disclosed is an anti-corrosion treatment method for a heat exchanger, in which even if an aluminum material-made heat exchanger having been flux-brazed by the NB process, in particular, an aluminum material-made heat exchanger to be used for automobile air conditioner is not subjected to a chemical conversion treatment in advance, not only corrosion resistance can be significantly enhanced without impairing hydrophilicity, but deodorizing properties can be enhanced. The anti-corrosion treatment method for an aluminum material-made heat exchanger includes bringing an aluminum material-made heat exchanger having been flux-brazed by the Nocolok brazing process into contact with a hydrophilic treatment liquid and then applying a baking treatment, thereby forming a hydrophilic film on the surface of the aluminum material-made heat exchanger, wherein the hydrophilic treatment liquid contains a hydrophilic resin and a lithium ion, and a lithium concentration in the hydrophilic film is from 0.05 to 25% by mass.
