And Graham being English definitely makes him an expert in spreading the particulate matter. We love him anyway.

As regards the coating, we had a similar question posed many years ago by an avionics manufacturer. As we considered the Tg might be too low with HumiSeal 1B31, they tried and switched to HumiSeal 1B73. Still an acrylic with the benefits thereof, but a slightly higher Tg. However, IT DEPENDS(tm) (Cha Ching!) on the amount of particulate matter that you are trying to resist - can the enclosure be improved? Most coatings have, by the nature of their task, to be soft and pliable. However, 1A20 might just do what you are looking for, but its a ******* to work with. As for Dewey - he's by far the PUNNIEST man I know. Kindest regards Graham Naisbitt [log in to unmask] www.gen3systems.com Phone: +44 (0)12 5252 1500 Mobile: +44 (0) 79 6858 2121 --------------------------------------------------- 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 ----------------------------------------------------- --------------------------------------------------- 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 -----------------------------------------------------
