Hi Martina, We use WaferGrip (by Dynatex) high temperature glue, it works not bad, and resist at least 105 C. NIKKA SEIKO also produces some waxes which stand about 100 C, but I didn't try them. Another high temperature wax available in Logitech company, but it applied by handily operation. If you get responses with other options, I will glad to hear about them. Sincerely, Vladimir Krasniansky, Process Engineer, Gal-El (MMIC); 100, Yitzhak Hanassi Blvd., P.O. Box 330 Ashdod 77102, ISRAEL.
