New Orleans, Louisiana -- Bayer MaterialScience said UV-curable polyurethane dispersions (PUDs) can be used as efficient alternatives to currently-used aerospace topcoats.
Current coatings used on aircraft require 72 h to cure before the plane can be moved outside the hangar, BMS said in a 17 Feb news release. Therefore, there is a desire in the industry to increase productivity and efficiency by decreasing the "dry-to-fly" time.
BMS scientists formulated and tested UV-curable PUDs as possible alternatives to conventional aerospace topcoats. It said these meet "the flexibility, chemical-resistance and weatherability specifications that result in decreased curing time and increased productivity."
Todd Williams, senior associate scientist, presented BMS's findings in a 16 Feb presentation during the Waterborne Symposium 2012 in New Orleans, Louisiana. "Based on our research, we determined that UV-PUD binders are a promising technology for the aerospace coatings market," Williams said.
