U.S. EPA Approves Use of Kraton’s New Anti-Microbial Coating Technology at Delta Airlines

Kraton Corporation announced that the U.S. Environmental Protection Agency (EPA) approved a public health emergency exemption under Section 18 of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) submitted by the Georgia, Utah, and Minnesota Departments of Agriculture for the deployment of BiaXam in specific applications. 

The EPA exemption will allow Delta Air Lines to use BiaXam in specific applications in these states to protect against the SARS-CoV-2 virus.

BiaXam sulfonated block copolymer is a solid yet transparent material that can provide long-lasting antimicrobial protection on public surfaces, according to Kraton. 

This technology can kill up to 99.999% of the SARS-CoV-2 virus under laboratory conditions, with continued protection for up to 200 days, depending on use, exposure, and cleaning methods, according to Kraton, who developed the BiaXam technology as part of its sulfonated polymer product line and is currently seeking regulatory approvals in other jurisdictions, including countries outside of the United States. 

Delta will be the launch customer for BiaXam. The airline’s kiosks and counters in Atlanta, Salt Lake City, and Minneapolis will be the first to feature the product. Delta said it will look to expand its use to other airports pending further regulatory approval.

“We believe that BiaXam is unique due to both its efficacy, durable and residual properties that distinguish it from other technologies that require a more frequent application or treatment,” said Kevin M. Fogarty, Kraton’s president, and CEO. “We are not aware of other available technologies that provide the long-lasting, durable protection that BiaXam can offer. 

“Moreover, while other antimicrobial products are based upon a chemical as the active ingredient, BiaXam is a polymer, and the antimicrobial properties are an inherent feature of the polymer design,” he added.

“This new technology offers an exciting new layer of protection that will help us maintain and enhance the effectiveness and efficiency of our protocols and build customer confidence both during the pandemic and beyond,” said Mike Medeiros, VP of Global Cleanliness at Delta.

The BiaXam patent-pending technology can be coated on various substrates and surfaces made up of plastic, metal, and glass. 

It can also be applied as a versatile peel-and-stick film. 

The efficacy of Kraton’s BiaXam technology has been thoroughly studied by organizations, including Boston University’s National Emerging Infectious Diseases Laboratories (NEIDL), North Carolina State University, University of Texas Medical Branch (UTMB) at Galveston, and Syngene International Ltd., the company said.  

The testing performed at the UTMB and Boston University BSL-4 laboratories demonstrated BiaXam to be effective against SARS-CoV-2, according to Kraton. 

“We intend to advance the BiaXam technology platform for several potential applications and seek appropriate regulatory approvals,” said Dr. Vijay Mhetar, senior VP and chief technology officer. “Specifically, we are strategically partnering with several renowned hospitals and universities to identify potential opportunities to improve patient safety.”

BiaXam will need to complete regulatory approvals before it is offered to the general public for this and other purposes, Kraton said.
