“I need some help in determining the applicability of post forming powder coated aluminum products. Briefly, what is the current “State of the Art” technology, and what are the restrictions?”
“Many powder formulations have post-forming capabilities. The typical resins used are epoxy and polyester. Although both of these can be formulated for post forming, they have different UV resistance characteristics. This highlights the need for a well defined powder coating material specification that lists ALL your requirements so that your coating selection can achieve these requirements. This will insure that you purchase the powder coating that fits your requirements and not a coating that a salesman wants to sell you.
There aren’t any “State of the Art” coatings for a post-forming environment. Powder coatings have been used for years in applications where a zero “T bend” is a requirement.”
