    Abstract: Protective and residual organic coatings are stripped from a surface by substantially sealing the surface from the atmosphere to provide a stripping zone, forming a stream of gaseous stripping composition in an evaporation zone, contacting the surface with the stripping composition in the gaseous state at about ambient temperature and recirculating the gaseous mixture from the stripping zone to the evaporating zone and back to the stripping zone to rapidly increase the concentration of gaseous stripping composition in the stripping zone. Optionally the surface may be rinsed by raising the temperature of the gaseous stripping composition slightly above ambient temperature, whereby the gaseous stripping composition condenses on the surface and flushes the surface free of adhering particles. This process is useful for objects which can be placed in a stripping zone and substantially sealed from the atmosphere, especially objects having an irregular surface, and also for interior surfaces which can be substantially sealed from the atmosphere, including extensive surfaces such as those of storage tanks, tank cars and the holds and ballast tanks of ships.

    Abstract: Coatings, such as paint or oil, are stripped from the surface of a coated object by circulating a stream of a stripping composition in a gaseous state at ambient temperature and pressure into contact with the surface. The stripping composition is normally a liquid at ambient temperature and pressure and has a partial pressure of at least 5 mm of Hg. at ambient conditions. The contacting procedure is conducted substantially in the absence on the surface of liquid condensate of the stripping composition.

    Abstract: An ultraviolet treatment of organic titanates on metal surfaces to increase adhesion of inks and coatings is disclosed wherein the adhesion of subsequently applied inks and coatings is improved. The method includes an initial treatment of the lubricated metal substrate with an organic titanate such as tetrakis (2-ethyl hexyl) titanate and then exposing same to ultraviolet light to accelerate the reaction of the titanate with the metal surface.

    Abstract: A coating for metal articles which is resistant to chemical and mechanical attack is produced by first depositing a highly homogeneous, finely crystalline zinc layer on the base article; then producing a chromate layer on the zinc deposit by submerging the article in a chromic acid solution with a PH value of less than 2, preferably around 1.5; then, after rinsing the remnants of the chromic acid solution from the article, coating the rinse wet article in a dispersion of synthetic material and in the presence of a reducing agent, with synthetic materials of nonwaxlike character; and then subjecting the base article with the synthetic coating thereon to a thermal treatment in order to reduce the hexavalent chromium of the chromate layer to trivalent chromium and to harden the synthetic coating by drying.
