Abstract: Coating compositions and methods of their use are described herein for the reduction of corrosion in imbedded metal structures. The coatings are applied as liquids to an external surface of a substrate in which the metal structures are imbedded. The coatings are subsequently allowed to dry. The liquid applied coatings provide galvanic protection to the imbedded metal structures. Continued protection can be maintained with periodic reapplication of the coating compositions, as necessary, to maintain electrical continuity. Because the coatings may be applied using methods similar to standard paints, and because the coatings are applied to external surfaces of the substrates in which the metal structures are imbedded, the corresponding corrosion protection may be easily maintained. The coating compositions are particularly useful in the protection of metal-reinforced concrete.

Abstract: A hydrotalcite-type compound [M2+1−xM3+x(OH)2]x+[An−x/nmH2O]x− (where M2+ is a bivalent metal ion, M3+ is a trivalent metal ion, An− is an anion of valency n and 0<x≦0.33) is mixed with a binder such as colloidal silica to obtain a film-forming composition. The film-forming composition can form strong coatings that exhibit hydrophilic properties. The hydrotalcite-type compound can disperse in water under acidic conditions, thus allowing its mixture with the binder. Once the hydrotalcite-type compound is dispersed with the acid, it can then be diluted with water or an alcohol. This makes it possible to obtain coatings containing titanium oxide, etc., that constantly exhibit hydrophilic properties with or without light irradiation.
