Evonik's Coating Additives business line has developed a new tool for the digital analysis of coated test samples: COATINO® Defect Detection (CDD), that precisely and objectively detects and evaluates coating defects. Within a few seconds the system delivers quantifiable results. So far, laboratory personnel have had to rely on visually evaluating samples when developing a new formulation. Many samples must be carefully compared and evaluated. The Defect Detection saves lab experts a lot of time: 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.

COATINO 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. The Coating Additives business line 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.
