AkzoNobel develops marine fouling prevention solution based on UV-LED technology

AkzoNobel is to develop a revolutionary fouling prevention technology which uses ultraviolet light-emitting diodes (UV-LED). The pioneering solution – which uses underlying technology developed by Royal Philips – will be applied to underwater surfaces to eliminate fouling growth.

By teaming up AkzoNobel’s surface protection and adhesion know-how with Royal Philips’ unrivalled capabilities and intellectual property in UV-LED lighting and electronics, the two companies are aiming to develop an economically viable solution for underwater fouling prevention.

The innovation will integrate UV light-emitting diodes in a protective coating scheme which will allow for the UV light to be emitted from the coating surface, providing the total prevention of biofouling accumulation on the surface of the protected area.

The fully biocide-free solution claims to provide groundbreaking performance and offer complete fouling prevention to the hulls of ships and boats. The total control of biofouling represents a substantial economic and environmental benefit.

“In our Sustainable Fouling Control initiative, we actively explore and develop alternatives to biocidal-based solutions,” said Oscar Wezenbeek, Director of AkzoNobel Marine and Protective Coatings. “This development is a great proof point of our continuous focus on delivering eco-friendly solutions to our customers.”

Despite the complexities of this project, AkzoNobel is again confident they will be overcome and ultimately expects the technology to completely revolutionize the fouling control industry. Initially, the focus will be on applications for ships, yachts and offshore assets, but the project could potentially be extended to include other surfaces challenged by bio-fouling issues.

“This unique project is fully aligned with AkzoNobel’s continuous focus on innovation,” explained Klaas Kruithof, AkzoNobel’s Chief Technology Officer. “In our quest to not only protect and color, but also functionalize surfaces, 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 realization of this transformative innovation, which we intend to initially market ourselves and consider licensing out to third parties for large-scale adoption.”
