Bio-based Functional Coatings Reach Commercial Maturity for Marine Use
A significant milestone in the decarbonization of the maritime industry has been reached as AkzoNobel and Arkema announce the full commercial maturity of their joint bio-based marine coating solution. Following extensive sea trials and formulation refinement, the companies have validated a high-performance functional coating that relies on renewable chemistry without compromising the rigorous durability standards required for oceangoing vessels.
Bridging the Performance Gap
Historically, the marine sector has hesitated to adopt bio-based alternatives due to concerns regarding hydrolysis and resistance to saltwater corrosion. However, this new commercial offering leverages Arkemaâs advanced bio-circular materialsâspecifically derived from castor oilâto create a resin system that matches the mechanical properties of traditional fossil-based epoxies and polyurethanes.
The collaboration integrates Arkemaâs high-performance Polyamide 11 chemistry into AkzoNobelâs proprietary marine coating formulations. The result is a hull coating that offers exceptional adhesion and impact resistance while significantly lowering the carbon footprint associated with the raw material extraction and production phases.
Targeting Scope 3 Emissions
The commercial release of this technology comes as the shipping industry faces tightening regulations from the International Maritime Organization (IMO) regarding carbon intensity. By switching to bio-based functional coatings, shipowners can directly address their Scope 3 emissions.
Unlike early experimental bioplastics that degraded too quickly in harsh marine environments, this mature technology provides a stable, long-lasting barrier. The formulation is designed to minimize drag, thereby improving fuel efficiency, while ensuring the biopolymer matrix remains intact over extended dry-docking intervals.
Executives from both companies highlighted that this launch moves beyond pilot phases, offering a scalable supply chain capable of servicing global fleets immediately. This development signals a shift where renewable feedstocks are no longer niche additives but central components in heavy-duty industrial applications.
