Aluminum Anodizing Chemicals
When an aluminum part is used as the anode in an electrolytic cell, a controlled oxide film is formed. This process, known as anodizing, enables aluminum to be used in a number of ways for which it might not otherwise be suitable. Anodized aluminum can be found in automotive, aerospace, construction, decorative items, sporting good equipment and many other applications. The anodizing process forms an oxide film which grows from the bass metal as an integral part of the metal. This film imparts a hard, corrosion and abrasion resistant coating with excellent wear properties. The coating, porous in nature can be dyed numerous colors. The following U.S. Specialty products are designed to process aluminum for anodizing and coloring.
| Cleaners: | |
| Specialty 740 | A superior, long lasting cleaner. Non-silicated, non-caustic has tremendous capacity for penetrating machine, petroleum and water-soluble surface soils. Mildly foaming formulation. |
| Specialty 760 | Mildly acetic, phosphoric cleaner. Removes light soils and polishing compounds while conditioning and brightening the part surface. |
| Etchants: | |
| Specialty 835 | Our top selling alkaline etchant, which uniformly and rapidly etches aluminum alloys. It contains ingredients, which minimize the formation of scale on tank walls and heating elements to reduce maintenance costs and time. |
| Specialty 839 | An etch additive for self-made etch solutions that aides in the chelation and rinsing properties that are lacking in straight caustic blends. |
| Specialty 861 | A liquid acidic aluminum cleaner and conditioner. The unique formulation removes oils, grease, dirt and oxides while imparting mild etch to the surface of most aluminum alloys. Anodized parts treated with Specialty 861 appear bright and shiny, not matte. |
| Deoxidize/Desmut: | |
| Specialty 982 | Our top selling chrome-free liquid deoxidizer for a wide range of alloys. It operates at room temperature and is also an excellent deox for aluminum alloys prior to chromating. |
| Hard Coat Additive: | |
| Ano-EE | Liquid additive for higher temperature Type III anodizing. |
