Silicone coating on paper and plastic

AppNote XRF1140: analysis of silicone coating on paper and plastic

Background

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. During the coating process the amount of silicone coating, usually expressed as a coat weight in g/m², must be periodically measured in order to ensure the proper physical properties of the product. When coating is too heavy silicone material is needlessly wasted, while too little coating may not meet the product spec. In order to achieve reliable QA/QC, Rigaku offers the NEX QC EDXRF analyzer. Simple to operate, the NEX QC gives the QC technician an ideal tool for quickly checking silicone coat weight in order to maintain the highest product quality with minimal costs.
