Arnaud, Not cheap, but FTIR is an excellent method for detecting silicones. Regards, Bev -----Original Message----- From: TechNet <[log in to unmask]> On Behalf Of GRIVON Arnaud Sent: Tuesday, January 7, 2020 9:00 AM To: [log in to unmask] Subject: [TN] [COM] Evaluating/Monitoring Silicone Contamination Happy New Year TechNet ! Here is a first query for 2020... We all know about the need of carefully segregate acrylic/urethane from silicone conformal coatings, but how about evidencing and demonstrating (say for an angry auditor) the actual lack of silicone cross-contamination on toolings, ovens and workspaces ? Are you aware of any reliable test system to perform silicone contamination evaluations? What are their principles and related test methods & acceptance criteria? It looks like some suppliers offer Surface Silicone Contamination Test Kits : - Henniker Plasma<https://plasmatreatment.co.uk/wp-content/uploads/2016/09/Henniker-Pla sma-Technology-Overview.pdf> : https://plasmatreatment.co.uk/henniker-plasma-technology/products/surface-te st-equipment/test-for-surface-silicone-contamination/ - Anderson Materials Evaluation : http://www.andersonmaterials.com/test_methods/testing-facilities-for-silicon e-contamination.html#<http://www.andersonmaterials.com/test_methods/testing- facilities-for-silicone-contamination.html> Any practice of such test kits and return of experience to share? Thanks in advance for your feedbacks. Best regards, Arnaud Grivon
