One-component, UV-curable waterborne polyurethane coatings make a splash

Chicago, May 1, 2012 — As the coatings industry continues to seek ways to lessen its impact on the environment, ultraviolet- (UV) curable polyurethane dispersions (PUDs) have emerged as a viable solution. This coatings technology offers lower volatile organic compounds (VOCs) and volatile hazardous air pollutants (VHAPS) than solventborne coatings, while still providing the performance characteristics necessary for a variety of demanding applications.

"As a leader in polyurethane chemistry, we understand the coatings industry's rigorous environmental, economic and performance requirements," said John Brandt, head of business development, UV & Wood Coatings NAFTA, Bayer MaterialScience LLC. "Coatings based on our one-component, UV-curable waterborne PUDs can help coatings formulators and end-users meet all of these challenging requirements."

Brandt will explore the benefits of UV-curable waterborne PUDs in his technical presentation, "A Sustainable Chemistry: One-Component, UV-Curable Waterborne Polyurethane Coatings," at 10 a.m., May 1, during RadTech UV/EB 2012.

Brandt will discuss the chemistry behind UV-curable waterborne PUDs, which have been nominated for a 2012 Presidential Green Chemistry Challenge award. He will also highlight the evolution of this technology and why the wood coatings, site-applied floor coatings and aerospace markets were among the first to embrace this customizable technology.

Brandt will also focus on the topic of sustainability from a coatings perspective. More specifically, he will address the industry's sustainability drivers (including regulatory compliance, energy efficiency and use of renewable materials, among others), the components of sustainability and the Life Cycle Analysis (LCA) approach to measuring UV coatings versus other technologies.

RadTech attendees are encouraged to stop by Bayer MaterialScience's exhibit (#400) during the conference to further discuss these technologies.
