Accurate monitoring of high-tech coatings – Efficient testing along the entire line

Today, paint manufacturers develop highly complex paint systems with optimized properties for the respective application. On the other hand, the specifications of such high-tech coatings must be adhered to ever more accurate to ensure that they deliver consistent quality. Due to the complexity of such paint systems, the coating thickness of the high-tech paints must be checked as early as possible in the process.

OptiSense has developed a unique expertise in high-tech coating thickness testing that exceeds even the most stringent specifications and highest quality requirements of your clients.


The German Business Award goes to OptiSense

OptiSense has been granted the German Business Award 2023. This award recognizes companies from all over Germany for their innovation and excellence in their business practices as well as their outstanding overall performance.

OptiSense is the only German company in the field of coating thickness measurement to receive the award for strong innovations, sustained top performance and its outstanding market position in the sensor industry.

Stoz measures wet paint on chrome prior to baking

Whether piano finish, metallic effects or anti-slip coatings: Painting on chrome is a particular challenge - especially when it comes to accurately checking the coating thickness in the wet state. The management team at Stoz GmbH, Managing Director Maximilian Stoz and department heads Holger Salzmann, Jürgen Andrusch and Steffen Fessele, explain how they accomplished this with the PaintChecker Mobile.

Coating thickness sensors with built-in time saver

The commissioning of measurement and test equipment in a coating plant should be as simple and efficient as possible. In the sensor industry, too, there are solutions that speed up the job of design engineers and installers. An example are the industrial sensors from OptiSense with a completely new design that eliminates the need for any mounting bracket. It saves time during installation and simplifies assembly.
