Engineering Properties

The CompCote® Finish is more corrosion resistant


The CompCote® finish exceeds the corrosion resistance of conventional anodic oxide finishes without the use of heavy metal seals.

Salt Spray, ASTM B117, Corrosion Resistance Results – Type II and Type III - CompCote® A and CompCote® H


Salt Spray, ASTM B117, Corrosion Resistance Results - Type I - CompCote® B.

The CompCote® H Finish withstands extreme environments

The CompCote® H finish outperforms conventional Type III hardanodic oxides in extremely aggressive environments such as heavy metal halides used in the overhead lighting industry. Two of the salts to which CompCote® H was exposed were Cesium Chloride and Cesium Iodide.
