Powder Application Technology

Coating products with organic powder paints is the most environmentally-friendly of all painting technologies and is also the most gentle on resources. The painting technology centre at Fraunhofer IPA is equipped with adaptable industrial-scale systems. The extended use of powder paints in the area of highly-productive and high-quality coatings calls for new design concepts for the application and closed-loop circulation process. Consequently, the R&D work we carry out under realistic production conditions in our powder coating centre focuses on the following topics:

• High-efficiency and low-separation powder spray systems
• Process-reliable closed-loop circulation of powder materials
• Application of powder coatings to heat-sensitive or non-metallic components
• High-speed coating without the use of guns (TransApp® technique)

Services:

• Characterization and optimization of paint atomization processes and paint transport
• Comparisons of processes
• New selective coating method without the need for masking
• Substitution of conventional powder coating systems by ultra-compact, energy-efficient plants without spray units
• Development of solutions for paint drying and curing processes that save time and energy
• In-line process monitoring and control of pre-treatment and coating processes

Customer benefits:

• Supplier-independent tests conducted by experts
• Quality- and cost-optimized painting plants
