Better Silicone Coat Weight Control

 Meet the next-generation NEX QC II Series for silicone coating quality control

Rigaku NEX QC II Series, benchtop EDXRF elemental analyzers.

Why silicone coat weight matters

Maintaining the right silicone coat weight is important for release performance, material use, and production efficiency. Applying too little can compromise performance, while too much increases material costs. 

Fast, dependable measurement helps production and QC teams verify silicone coat weight, maintain consistency, and reduce unnecessary material use and waste.

Silicone coat weight analysis by EDXRF

EDXRF is widely used across the silicone coatings industry to measure coat weight, thickness, and composition in release coatings, barrier layers, and other silicone-coated materials. The NEX QC II Series provides a practical solution for routine quality control, combining simple operation with low operating costs and flexible analysis for a range of applications.

  • Release liners
  • Labels and tapes
  • Food packaging
  • Medical packaging
  • Hygiene products
  • Films and converting
  • Vacuum-formed products

Talk to an expert

Every coating operation is different. But goals are often the same. Catch issues early, run closer to your target, ensure consistency, avoid downtime, and reduce waste. Contact us to discuss coat weight control strategies or talk through a specific line setup.

The complete QC approach

Rigaku EDXRF supports faster verification and better silicone coat weight control.


Quick at-line or lab verification NEX QC II Series

The latest generation of our benchtop system improves how at-line measurements fit into your process. They provide faster results for quicker decisions, easier operation for production and QC teams, and improved performance for demanding measurements. This makes it practical to use at-line validation alongside real-time monitoring.

  • Rapid silicone coating thickness and composition
  • Ultra-low silicone coating weights
  • Measurement of Sn, Bi, Ti, Pt, etc., in metal-catalyzed silicone release coatings
  • Silicone determination without helium or special sample cups
  • Easy sample prep by simply placing a test coupon in the analysis chamber
  • Simple, easy operation, and built-in printer for convenience
  • Dynamic mineralogy variation corrections, no taring required
  • Provides additional audit documentation

In-line coat weight profiling NEX LS

For operations requiring real-time process visibility, the NEX LS provides continuous in-line silicone coat weight measurement for roll-to-roll applications.

  • Continuous monitoring and control, reducing at-line checks
  • Cross-direction and machine-direction data for the entire roll
  • Immediate defect detection as the roll is being produced
  • Roll reporting and data logging for traceability and audits
  • Measurement capability for web widths up to 2365 mm
  • Dynamic mineralogy variation corrections, no taring required
  • Consistent performance, regardless of substrate color or composition variations (e.g., clay-coated paper)

Designed for real production environments

What complete QC visibility provides Run closer to target with less waste

With full visibility across your process, you can: 

  • Reduce over-coating and shrink safety margins
  • Lower raw material consumption
  • Improve coating uniformity across the roll
  • Reduce scrap and off-spec production
  • Speed up startups and reduce manual checks
