Abstract: A transparent, non-yellowing, polymer-clay, concrete sealer and methods for making and applying the same. The disclosed clay-based sealer provides a tough, ultraviolet-light-, temperature-, and abrasion-resistant layer that effectively protects surfaces from moisture penetration, staining, dirt, dust, and wear. The substrates to which the clay-based sealer may be applied include, but are not limited to, above and below grade concrete structures, brick, concrete masonry unit (CMU) block, grout, plaster, gunite, tile, and aggregate. The clay-based sealer may easily be applied with airless or air-assisted sprayers, or by roller, brush, or applicator pad. Once applied, the sealer requires minimal maintenance.

Abstract: The invention refers to a process for producing an anticorrosive coating in which a surface to be treated is brought into contact with an aqueous treatment solution containing chromium(III) ions and at least one phosphate compound and an organosol. The corrosive protection of metal surfaces, in particular those containing zinc and zinciferous surfaces with conversion layers is improved. The decorative and functional properties of the surfaces are retained or improved. In addition, the well-known problems associated with the use of compounds containing chromium(VI) or with multi-stage processes are avoided in which a passivation layer containing chromium ions and a sealing are applied one after the other.

Abstract: A method and composition for treating a metal surface, particularly steel, involves contacting the metal surface with a pretreating solution comprising a blend of water, an organo-functional silane, and a borate ester. The method involves first cleaning the metal surface, such as by using an alkaline cleaning agent, then rinsing prior to the application of the pretreating solution. The metal surface is dried and, either immediately thereafter or after some storage time, then contacted with a decorative finish, such as paint, completing the metal treatment method. The method and composition minimize rusting of the metal surface even if a relatively long period of time elapses between drying the pretreated metal surface and painting the metal surface. In addition, the method and composition provide good adhesion of the decorative finish to the metal surface.
