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.

② Pulsed heat input

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.

5.2 Intended Use

The coatmaster® Flex is intended exclusively for the measurement of coating thicknesses.

The device should only be used as a handheld device.

The device should not be mounted on a robot or fixture, or operated for an

extended period of time.

The instrument may only be operated and cleaned by trained personnel. The intended use also

includes compliance with these instructions and the maintenance intervals must be observed.

Have your device repaired only by qualified personnel and only with original spare parts. This

ensures that the safety of the device is maintained.

The device is not approved for operation in environments with potentially explosive

atmospheres.

Keep the device away from rain or moisture. Penetration of water into an electrical appliance

increases the risk of electric shock. Do not place the measurement device in a place where

components could come into contact with corrosive gases or salty air.

Do not block ventilation openings. The ventilation openings prevent the interior of the unit from

overheating.

Remove the battery before cleaning. Do not use solvents for cleaning, to avoid damaging the

housing surface. Use a clean, dry cloth.

In accordance with Directive 2012/19/EU, please take old parts to the appropriate recycling facilities

for proper disposal, reprocessing, and reuse. Never throw electrical equipment into the household

waste! By properly disposing of the electrical appliances, you help to protect valuable resources and

prevent possible negative effects on health and the environment, which could otherwise occur due

to improper waste disposal. Accessories and packaging should also be recycled in an environmentally

friendly manner.

5.3 Improper Use

Use not mentioned above or use that does not comply with the technical specifications, is considered

to be improper use. The operator is solely responsible for any damage caused by improper use.

The following applications are prohibited:

•

Use of the equipment in environments where liquids may get into the device.

•

Introduction of any objects into the coatmaster® Flex or similar devices.

•

Opening of the device, except for cleaning or changing filters and changing the plexiglass

pane. This only applies when the battery is not in place. Opening the device, other than for

standard maintenance operations (see section 11), voids the warranty and the

manufacturer assumes no liability.

The following safety instructions point out dangers of a general nature that may occur when handling

the device. The user must observe all the instructions listed to minimize possible hazards.

Additional warning messages can be found in this manual whenever the actions described could

result in hazards.

Symbol Description

The coatmaster® Flex with SpectralBlue contains a Xenon flash lamp. The Evaluation

of the photobiological safety of a Xenon flash light according to IEC-62471:2006

shows that the coatmaster Flex flash lamp falls under the exempt group and thus

does not pose any photobiological hazard.

CAUTION

Device damage may occur if the battery is changed during operation.

Never change the battery during operation, as this can lead to the device being

damaged.

◇

Always switch off the device before changing the battery.
