Biofouling breakthrough to harness UV-LED technology

The technology was developed by Royal Philips, and the anti-fouling solution will integrate UV light-emitting diodes in a protective coating scheme. This will allow for the UV light to be emitted from the coating surface, preventing biofouling accumulation on the protected area.

Klaas Kruithof, chief technology officer, AkzoNobel, said: “We actively look for complementary technologies and partners to innovate with. In this case, the combined capabilities and technology of Royal Philips and AkzoNobel will enable us to accelerate the realisation of this transformative innovation, which we intend to initially market ourselves and consider licensing out to third parties for large-scale adoption.”

Control of biofouling represents a substantial economic and environmental benefit for vessel owners and operators due to the improved fuel efficiency of clean hulls as well as maintenance savings. Initially, the focus for the biocide-free solution will be on applications for ships, yachts and offshore assets, but the project could potentially be extended to include other surfaces challenged by fouling issues.
