EDXRF Analysis of Silicone Coating on Paper and Plastic

Paper and plastic are coated with a thin layer of silicone during the manufacture of labels, tape or other adhesives, or as a barrier coating against air in the packaging of food, medical products and other materials. EDXRF analysis with the Rigaku NEX QC is shown to be an excellent tool for measuring silicone coating to ensure the proper physical properties of the product are maintained.
