We recently took on a job to powder coat subway acoustic panels with a copper metallic powder. We coated the first lot of parts, and the color and appearance on the parts is widely different from one part to another and even from one area of the part to another.
Now that we have had some in the field for a while, we are getting complaints about rust on the steel parts and peeling on the aluminum benches. Do you know what the cause is or how we can prevent these problems?
We recently started to run polyester urethane powders in our system and we are getting a lot of smoke and odor in the building. What’s causing the excess smoke from the oven? Is it harmful? How can we stop it?
