Happy Monday All, This has nothing to do with the ISS or Lawrence Welk :-) On occasion we get tiny bubbles in our moisture cure, polyurethane conformal coating. We know that if the humidity is high (seldom happens here in Western Washington) and you get the coating on a little thick the bubbles will form. I'm sure the coating skins over really fast in high humidity and then all those little volatiles can't get out creating tiny bubbles. My question is, are there any methods for removing these little bubbles once the coating is cured? Generally they are not bad enough to need rework but on occasion there are just too many to ignore. Thanks as usual for any help, KennyB --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 15.0 To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-615-7100 ext.2815 -----------------------------------------------------
