Hello, we use a polymer coating on steel and although it comes out of the salt/fog chamber fine, after about 24 hours it shows micro cracks. Any ideas? Thanks in advance.

Based on your most recent description, one of the things I would look at is the ratio of resin to hardener used for the powder coating. If the paint is being cured properly (time and temperature), then it is possible that the ratio is not correct, making the part more susceptible to water absorption and subsequent shrinkage/cracking. I suggest discussing this issue with your paint supplier or a knowledgeable independent test lab.
