DFT Testing for Paintings and Coatings

Applied Technical Services performs DFT testing for painting and coatings to uncover information on the coating’s quality and performance.

What is Dry Film Thickness and Dry Film Thickness Testing?

Dry film thickness testing evaluates the thickness of a single layer or multiple layers of coating. The test provides information on the protective qualities of coatings by ensuring that coating thickness abides by ASTM standards and industry guidelines. Coating thickness directly affects a coating’s protective qualities, so thicker coaters provide greater protection from corrosive elements than thinner coatings.

Magnetic Pull-Off Thickness Gauge

Magnetic pull-off gauges measure the magnetic between the coated material and the magnetic gauge. The magnetic attraction decreases as the coating thickness increases.

Magnetic Electromagnetic Induction Gauge

Electromagnetic induction gauges measure the coating thickness of non-magnetic materials by evaluating the changes in the magnetic field as the gauge contacts the coating.

Eddy Current Film Thickness Gauge

Eddy current gauges measure non-conductive coatings on non-magnetic substrates such as aluminum, brass, and copper. The gauges evaluate the strength of the eddy current to determine the coating’s thickness. The eddy current’s strength decreases as the coating’s thickness increases.

Understanding Dry Film Thickness Gauges

Dry film thickness gauges are sensitive instruments that require application-specific procedures and calibrations. We consider the following factors when conducting dry film thickness tests.
