Mil spec MIL-A-8625 requires sealing of thin anodized coatings (Type I and Type II); sealing is allowed as an option for thick coatings (Type III). By "effectively cured coating" is meant that the coating is hard (greater than "H" pencil hardness), and does not blush or haze upon exposure to water. There are many different applications for the types of clear anodized aluminum. The Willis Tower (once known as the Sears Tower) in Chicago used anodized aluminum. Resistance to mar is tested by rubbing a wooden tongue depressor at 45 degree angle back and forth five times on the coated surface. The results are set forth in Table 2. No matter what you’re dealing with involves architecture or designing consumer goods, whenever you require a durable, appealing, and lightweight metal material, clear anodized aluminum will provide you with the most versatile solutions. Permacel 99 tape is applied over the area of cuts by pressing down firmly against the coating to eliminate voids and air pockets. Amino silanes in particular have been suggested in the prior art for coatings of this type, but have been found by the present inventors to be of limited effectiveness on anodized aluminum. In addition to the primary film-forming acrylic or polyester resins, the compositions of the present inventions may include other modifying or diluent resins. The above ingredients were blended in the above-listed order, diluted with solvent to 35 percent solids, and spray applied. A coating composition and method for protecting anodized aluminum, and the coated product are disclosed, wherein the coating comprises a crosslinking agent; a film-forming resin selected from the group consisting of polyester polymers, thermosetting acrylic polymers, and mixtures thereof; and an epoxy silane. This resin was polymerized to an acid value of 8.3 and a hydroxyl value of 179. Additionally, on top of its increased durability, the anodized aluminum won’t chip, flake, or peel, especially when it’s processed to have a clear appearance. All clear anodized aluminum will be brought clean and ready for the appropriate use. 4,879,345 (Connelly et al.)

Moreover, it’s lightweight quality can also help out in solving a variety of design issues. Depending on what parts you want to de-anodize, it may require completely disassembling your vehicle to make it happen. Detergent resistance is tested by immersing the samples in a 2% detergent solution at 100° F. (38° C.) for 72 hours. The coating was spray applied and cured in the same manner as described in Example 6. $24.95 $ 24. In general, anodized clear aluminum is one of the toughest and most versatile metal products on the market. The coating was spray applied and cured in the same manner as described in Example 7. 75. For the dry adhesion, boiling water adhesion, and 24 hour soak adhesion tests, the coating is scribed with eleven parallel cuts through the film 1/16 inch apart. When used on anodized aluminum surfaces, however, most of these conventional coating compositions do not exhibit the desired degree of adhesion to the anodized surface. However, oftentimes there is no specification. Gamma-glycidoxypropyltrimethoxysilane available as "A-187" from Union Carbide. And this is due to the anodization process being performed with controlled oxidation, the finished product will never get weathered or rust. Compositions containing thermosetting acrylic polymers have been found to be preferred for producing an excellent combination of both adhesion and hardness, particularly when the acrylic polymer is an acrylic/acrylamide copolymer. If no marking of the coated surface results, the performance is rated "good". Classic Car Detailing: Buffing.
