Arnaud,
Not cheap, but FTIR is an excellent method for detecting silicones.

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

st-equipment/test-for-surface-silicone-contamination/

-          Anderson Materials Evaluation :

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
