EDXRF / XRF for Silicone Coat Weight

Silicone on paper or plastic: denesting, release and barrier coatings

Silicone oil coatings serve applications from mold release to protective barriers. X-ray Fluorescence (XRF), a standard technique across the coatings industry, is used to determine coating weight, thickness and/or composition.

Silicone coatingsNEX QC

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 specification. In order to achieve reliable QA/QC, Rigaku offers the NEX QC energy dispersive X-ray fluorescence (EDXRF) analyzer. Simple to operate, the NEX QC EDXRF gives the QC technician an ideal tool for quickly checking silicone coat weight in order to maintain the highest product quality with minimal costs.

Process coatings analysis NEX LS

The Rigaku NEX LS is a scanning measurement system comprised of an EDXRF measurement head mounted to a motorized frame, which transports the head back and forth across a moving web while transmitting the cross-machine direction (CD) measurements to a control box and industrial touch screen computer. Data are presented in real time as cross web and down web graphical profiles. Featuring advanced 3rd generation energy dispersive X-ray fluorescence (EDXRF) technology, the Rigaku NEX LS represents the next evolution of scanning process silicone coatings analyzers for web applications.
