You should also make sure you have an oil and water trap and in-line drier feeding your system.

Paul Paul Edwards Process/Quality Engineering Surface Art Engineering -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Blair Hogg Sent: Wednesday, August 29, 2012 7:04 AM To: [log in to unmask] Subject: [TN] Cloudy Conformal Coating I'm hoping that Technetters can share some light on an issue that we occasionally experience here - we coat some of our boards with 1B73 conformal coating, for some we have a spary machine, others a sprayed by hand. Every so often we will process some board through coating and they will have a cloudy / milky appearance in the coating. We have been told previously that this happens when humidity is up, since our manual spray coating area is not in an air-conditioned environment. Anyone else ever have this problem? How did you fix it? Thanks, Blair ______________________________________________________________________ This email has been scanned by the Symantec Email Security.cloud service.
