Abstract: A process for removing paint from rubber surfaces employing an acidic stripping solution comprising sulfuric acid and preferably one or more anionic wetting agents.

Abstract: A Mannich base and thiourea inhibitor composition and method of inhibiting the acid attack by aqueous hydrofluoric acid on ferrous metal surfaces, and in particular, highly reactive ferrous metal surfaces.

Abstract: Eradication of oak and other woody plants is obtained through a synergistic effect derived from the application of herbicides of two different groups wherein the first group consists of a chlorinated aliphatic acid which can be trichloroacetic acid or 2,2-dichloropropionic acid; and the second group consists of 2,4-dichlorophenoxyacetic acid, 2,4,5-trichlorophenoxyacetic acid, 2,4-dichlorophenoxypropionic acid, 2,4,5-trichlorophenoxypropionic acid, 2-methyl-4-chlorophenoxyacetic acid, 3,6-dichloro-o-anisic acid, 2,3,6-trichlorobenzoic acid and 4-amino-3,5,6-trichloropicolinic acid.

Abstract: In the continuous strand method of processing high carbon steel wire for subsequent cold deformation, a zinc phosphate conversion coating is rapidly formed on the steel surface to aid in the subsequent deformation by contacting the steel surface with an aqueous acidic coating solution comprising phosphate, zinc and nitrate.

Abstract: A coating solution comprising trivalent chromium and one or more cations selected from the group consisting of manganese, bismuth, antimony tin, zinc and molybdenum is employed in a process wherein the solution is contacted with a metallic surface to form a corrosion resistant coating. The coating can be force dried or can be treated with a passivating solution.
