A new energy dispersive X-ray fluorescence (EDXRF) method allows the measurement of silicone coat weight on paper and plastic. The method demonstrates the effectiveness of the manufacturer’s bench-top EDXRF analyzer as a tool during the QC process in producing coated product. The method described employs EDXRF spectrometry as an affordable means of optimizing quality while minimizing costs and reducing product rejection and waste.
Paper and plastic are coated with a thin layer of silicone as a release coating in the manufacture of tape or other adhesives, or as a barrier coating for protection against air in the packaging of food and other materials. When coating is too heavy silicone material is wasted, while too little coating may not meet the product requirements. The analyzer enables quick checking of the silicone coat weight in order to maintain the highest product quality with minimal costs.
