Bernhard Resch is a Scientist II with Evonik Corporation’s Coating Additives Business Line. He has extensive powder coatings experience having worked for thirteen years with TIGER Drylac and seven years with Akzo Nobel before joining Evonik. His experience in managing production and labs as well as formulating powder coatings and trouble-shooting customer problems gives him broad understanding of powder coatings raw materials, manufacturing, and application. He has a degree in Chemical Industrial Engineering from Austria.



Novel Synthetic Silica for Matting Powder Coatings

Powder coatings have continued to broaden their application to protect a greater range of substrates. With this expansion, more chemistries are being developed for differing substrate compositions. These include lower-temperature cure to address heat-sensitive substrates and/or lower energy consumption to reduce cost. These applications also require aesthetics that require consistent matte finishes. Although there are several additives technologies being employed, the stringent need for greater uniformity in the final coating is still a challenge.
In this study, the presentation reviews the range of available additive technologies that are currently being employed for matting powder coatings, then introduces a novel synthetic silica technology and examines its impact on matting in powder coatings. The study will look at how this influences processing of powder, usage of the novel synthetic silica, main effects on matting and other performance characteristics of the final powder coating. The results will provide a comparable overview of how the new novel synthetic silica performs versus current available technologies.
