2Customer Requirements and Device Specification
Measuring the coating thickness early in the process is the key to documenting and controlling coating
processes, saving coating material, improving coating quality, and reducing running-in time and scrap.
Coating processes are highly sensitive to changes in environmental conditions; therefore, it is crucial
to have access to a thickness gauge that is easy to handle and works in an industrial environment.
The patented measurement process used by the coatmaster® Flex is non-contact (as opposed to
systems based on magnetic induction or ultrasound) and non-destructive. It can be applied on wet,
powder, and cured coatings, independently of the coating material, thickness, or color (including
white). In contrast to magnetic induction-based systems, the Flex device permits measurement of
coating thickness early in the process, i.e. directly after the application of the coating material, before
drying or curing. This allows to:
•Savings of 10%-30% coating material
•Reducing time for color changes
•Accelerating training of new personnel
•Avoiding cost-intense rejects & reworks
•Documenting coating processes
•Reducing environmental impacts
•Establishing industry 4.0 standards
•Online-connection to ERP-System
coatmaster® Flex is the most advanced measurement gauge for non-contact thickness measurements.
It outperforms any other photothermal, LED/laser-based, and ultrasound systems on the market in all
industrial relevant aspects. It requires minimal calibration and is insensitive to the angle and distance
of measurement. Its superior reliability, user-friendliness, safe usage, cost-effectiveness, precision,
and accuracy is highly appreciated by the major coating-line manufacturers, biggest paint
manufacturers, renowned experts and most importantly by coaters around the globe.

3Applications
The coatmaster® Flex is a flexible and robust handheld device for non-contact
measurement of coatings.
The coatmaster® Flex is unique and versatile and can be used in a wide variety of industries and
industrial sectors:
•Automotive
•Rail
•Aerospace
•Construction
•Furniture
•Profiles
•Wind Power
•Pipelines
•Medical/Technical
The coatmaster® Flex is particularly suitable for the following applications:
Powder paints
Due to control of coating thickness with Flex measurement, up to 30% of the
powder quantity can be saved. Measurement early in the process saves time
and reduces rework rates.
Wet paints
Precise measurements are possible even before drying. The measuring
equipment capability is guaranteed. This saves material and time, and ensures
quality.
Functional coatings
Thickness measurement of functional coatings (i.e. e-coats, adhesives, anti-
corrosive coatings) in wet and dried state. Highly accurate measurement even on
rough surfaces and for soft coatings.

4Functionality and Measuring Principle
The coatmaster® works according to the principle of advanced thermal optics (ATO). The surface of
the coating is heated with a light pulse. After brief heating by a few degrees, the surface is cooled
by heat conduction to deeper areas of the coating and the substrate. The cooling process on the
surface depends on the thermal properties of the coating and the substrate. The thinner the coating,
the faster the surface temperature decreases, providing it has a lower thermal conductivity than
the substrate. The thickness and thermal properties of the coating are derived from the dynamics
of the surface temperature.
Illustration of the measuring principle
① Flash lamp
② Pulsed heat input
③ Coatings
④ Substrate
⑤ IR radiation
⑥ IR sensor
Generally, coatings have a very irregular surface. Powder coatings before curing have an even rougher
surface, but can nevertheless be measured with the coatmaster® Flex. The properties of this roughness
are influenced by various factors, such as pre-treatment, the type and roughness of the substrate, the
type of coating (e.g. particle size, distribution, and chemical composition), and the exact conditions
(temperature distribution, baking time) during baking. The figure below shows a microscopic sketch of
this roughness. The TLT automatically compensates for the roughness described above, using an
optical averaging process. This allows a reliable determination of the coating thickness, even with
changing parameters.
