Brent, Don't know of any environmental issues but I would suggest you check for adhesion. My information is that Paralene seemingly will not work with no-clean processed assemblies, flux residues and all that. I am sure that someone at SCS will correct me if I am wrong. Paralene is a great process but it is expensive and time consuming being batch processing using a vacuum chamber. Unless otherwise specified, you may well find that a conventional coating will do that job equally well but more easily and at less cost.
