Wet Film Thickness Gauge for Conformal Coating Applications

Quick and Easy Measurement for Process Control

Wet film thickness measurement is a simple, reliable, and low-cost method of controlling conformal coating application while the material is still wet. By checking coverage before curing or drying, operators can identify issues early, make immediate adjustments, and prevent costly rework.

This proactive approach reduces waste, improves thickness accuracy, and helps maintain consistent coating performance across production batches.

Why Use Wet Film Thickness Gauges?

Wet film gauges provide value in several practical scenarios:

  • Non-destructive control – avoids cutting or damaging coated assemblies
  • Cost control – prevents over-application, reducing material use and weight
  • Immediate feedback – allows real-time adjustment during spraying, dipping, or brushing
  • Process validation – supports repeatable setup for operators and new product introductions

How Wet Film Thickness Gauges Work

Place the gauge directly onto the freshly applied coating so the stepped teeth contact the wet film. The last tooth that becomes coated indicates the wet film thickness.

To estimate the final dry film thickness, multiply the wet reading by the coating’s resin-solids percentage (as specified in the technical data sheet). Because the measurement takes only seconds, operators can maintain coatings within specification without waiting for cure or performing destructive testing.
