Automatic coating defect evaluation

“The new “Coatino Defect Detection” simplifies daily laboratory routine and frees them up for other important tasks,“ explains Oliver Kröhl, Head of Strategic Business Development at Coating Additives.

The Defect Detection, is aimed at paint formulators. They use a camera connected to the computer to photograph the coated samples. Within seconds the tool assesses them, using innovative image recognition methods.

Coating defects are evaluated to an accuracy of a tenth of a percent and processed in a clear manner. „For example, you can immediately see what percentage of the surface is affected by foam,“ says Philipp Isken, frim the Product Development team. “Reference formulations or blank samples can also be added to more clearly highlight the performance of the tested formulations. Based on the data, you can select the best formulation for the specific application.“

Detection of foam, cratering and incompatibilities

The defect detection was initially developed for pigmented systems in the architectural sector. For formulations with defoamers, the tool measures defects such as micro- and macrofoam, cratering, and incompatibilities. Evonik plans to add more industries and defect types to the tool. In the next stage of development, the Defect Detection will also independently suggest new formulations. Existing measurement results and the comparison of test series will serve as the data basis for these improved formulations.

The tool is easy to use: The application runs browser-based, so no software needs to be installed on the PC. The test series are documented in the system and can thus be retrieved at any time. An integrated help center provides detailed answers to all questions regarding the required hardware or individual application steps.

The Defect Detection is initially available free of charge to all registered users.
