Ioan, I can't address your question surrounding a soldermask choice. However, regarding the CC, of course I would have to reply that Parylene would be the best choice!

Dewey -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Ioan Tempea Sent: Tuesday, March 02, 2010 5:57 AM To: [log in to unmask] Subject: [TN] Special purpose soldermask Dear Technos, Is there any soldermask out there that would be preferred in high ammonia atmosphere? The boards are supposed to control the automation in farms, so they will see high ammonia and fumes and they will not be conformally coated. But if they were CC-ed, what would do best, acrylic or silicone? Thanks, Ioan Tempea, ing.
