Painting Anodized Aluminum
Because of the changes in our factory manufacturing sequence and production line, we are storing these parts for at least 13 hours before they are painted. In a management meeting, we discussed whether the storage of these parts before painting, or the anodizing is to blame for the paint adhesion problem. My personal feeling is that the problem is caused by contamination during storage. What do you think?
