advanced paint testing spray booth.

Multi-tone coatings in industrial coating processes have always been applied in several passes, where overspray had to be avoided manually. The new OFLA technology for overspray-free painting saves time and material. OFLA-compatible paints must meet high requirements, making their development a challenge for paint manufacturers. We built a machine that enables extensive paint testing in a controlled and safe environment.

reproducible and standardized.

Until now, two-tone coatings on cars, for example, were always applied in two passes. To prevent overspray, adjacent areas were taped off. That was a labor-intensive job in an unhealthy environment. Dürr, a leading manufacturer of coating technology, has developed a solution for applying paint without overspray: OFLA, or ‘Oversprayfreie Lackapplikation’. Manufacturers who supply suitable paints want to be able to test them first on standardized substrates. We therefore built a test machine with a painting robot that performs the required movements reproducibly and extremely accurately. Dürr’s EcoPaintJet system is integrated into our machine, which is completely made of stainless steel.

best formulation.

Our paint testing spray booth simulates the movements of a painting robot at the coating line in a controlled, dust-free laboratory environment. To compare different paint formulations, the machine always performs exactly the same movement with high precision. Our machine processes both water-based paints and solvent-based paints and is explosion-proof (ATEX) in view of the latter category. For ATEX certification, our design provides a constant flow of clean air into the test cell. This air flow removes solvent and thus lowers the concentration to a safe level. With the machine’s comprehensive control, paint manufacturers can easily define their test programs and parameters to find the best formulation for their coating products.
