Torsten, pH13!!! None of the ordinary polymers will withstand that. Are you sure of the requirement? I've never seen anything like that. I don't think even Parylene will be enough. I used Parylene C for military encapsulation of parts that had to pass salt spray for weeks, high temperatures and like, and we found that to withstand such a harsh environment , the Parylene had to be so thick, that the process had to be modified. The cost per package had been quite unrealistic. I would try ceramic spraying, that's probably your solution. There are lots of variants. I can't tell you which one suits best. Some are for electronics, others not. You better check the below URL and call the respective ceramic spray specialist. http://www.electronics.ca/publications/products/Coatings-for-Medical-Devices-%252d-Global-Strategic-Business-Report.html Good Luck Inge -------------------------------------------------- From: "Torsten Hagge" <[log in to unmask]> Sent: den 25 May 2010 12:30 To: <[log in to unmask]> Subject: [TN] Coating > Hi Technetters, > > looking for an conformal coating for electronics used in medical > application.
