This invention relates to a process for sealing an anodized aluminum surface by contacting the surface with an aqueous acidic sealing solution having dissolved therein zirconium and/or titanium and dissolved fluoride, said solution preferably including dissolved silicate and/or a dissolved thiourea compound, and including optionally a sealing auxiliary, the process being carried out at a temperature of no greater than about 40.degree. C.

Low temperature seal for anodized aluminum surfaces

Processes, bath compositions, concentrates for preparing the bath compositions, and a replenisher useful in the sealing of anodized aluminum and anodized aluminum alloys. The bath compositions contain nickel ion, fluoride ion, ammonium ion, and acetate ion.

Process and sealant compositions for sealing anodized aluminum

Cleaning solutions and processes for removing contaminating sealants used in the automotive and allied industries from water-insoluble surfaces. The cleaning solutions are aqueous solutions containing at least one C.sub.5 -C.sub.9 alkanoic acid, and optionally, other ingredients such as alkali metal phosphates, surfactants, etc.

Method for removing sealant contamination

An acidic aqueous solution for coating metallic substrates and consisting essentially of hexavalent chromium, reduced chromium, an alkylphenoxypoly(alkyleneoxy)ether and dispersed acrylic resin solids.
