We tested several polycarbonate-based materials for compatibility with disinfectants on the U.S. EPA “List N” for use against SARS-CoV-2, the coronavirus that causes COVID-19. Compatibility depended on whether the disinfectants were in continuous contact or periodically wiped. The results suggest certain inactive ingredients play key roles in promoting stress cracking.
Paul Nowatzki is a product expert at Covestro, supporting healthcare applications of polycarbonate. He manages new product development projects and is a technical consultant for business development. He has a Ph.D. in chemical engineering from Caltech and a bachelor's degree in chemical engineering from the University of Minnesota - Twin Cities.
