CompCote® enables direct polymer-metalbonding with suitable top coats due to its share of molecular polymers. This results in improved adhesion. It has excellent dyeability. Accelerated weathering tests with 200 hours of UV radiation show only a 1/3 of the color and brightness loss found in conventionally anodized films (both films anodized to a thickness of 10 µm, dyed black and sealed). Standard colors: black, titanium gray, blue, red, gold, green. Further colors upon request. |
| Smoothness The smooth surface and optimized microstructure created by CompCote® exhibits excellent tribologic behavior. |  |  | | Anodized 10 µm - Alloy 6061 T6 Roughness (Ra): 1007 Nanometer | CompCote® 10 µm - Alloy 6061 T6 Roughness (Ra): 733 Nanometer | |
It offers excellent anti-galling characteristics in various combinations as well as in friction tests. In some cases friction was reduced after repeating the same test because of a "self-lubricating" effect. Stick-slip effects are reduced. |
 Solid Bonding
CompCote® coatings are built up through transformation of the base material and are therefore optimally bonded with it. CompCote® grows into as well as out of the base material. | Film composition* | CompCote-A® | CompCote-H® | | Growth | 40% | 50% | | Depth Of Penetration | 60% | 50% | | * Approx. percentage, depends on alloy. |
Similar in concept to standard anodizing and hardcoating, the CompCote® process builds up a coating through anodic oxidation of the metal and simultaneous molecular bonding between the aluminum oxide structure and the polymer.
 |  | | Anodic oxide film TEM X 100K | CompCote® film TEM X 100K | The critical difference lies in the microstructure of the resulting material. Conventional anodized and hardcoat films tend to form a columnar structure. By comparison, CompCote® film has denser, cellular structure, increasing internal cohesion to make the material tougher.
