Chemical Conversion Coat Finish (Alodine)

Chem-film/Alodine is a chemical conversion process that prepares aluminum extrusions for field painting. It is a  multi-step cleaning and aluminum preparation process. First, it cleans the aluminum trim and then it acts as a protective coating until primer and paint can be applied. If your job requires field painting, a chemical conversion coating should be specified.
