“In particular, we were interested in IGP’s one-layer RAPID®Complete coating, which is based on DSM’s Uralac® Ultra technology. There are plenty of powder coatings available for wood and MDF furniture manufacturers, but we found only one that is a one-layer coating – without primer - which obviously increases productivity. At first, we were unsure of the quality of a one-layer coating, but DSM and IGP helped define the optimum layer thickness and curing parameters. It takes just three minutes at 130 °C for example, and the results are superb.”
IGP workshop accelerated adoption time
IGP clearly has a plenty of experience and expertise throughout the whole process of powder coatings – it’s even a ‘unique’ expertise when it comes to one-layer systems. To train Finima people, IGP held a one-day technical workshop at the MDF powder coating line at Finima. “Obviously, Finima were familiar with the basics of powder coatings,” says Jan Nühse, Team Leader Woodcoatings at IGP. “But the large range of parameters that affect the various aspects of the coating process means that there is a lot to master. For example, we showed how increasing the voltage in the electrostatic field by just 10kV affects powder delivery and improves quality. We also helped solve some practical challenges such as how to eliminate blistering on edges.”
