About SeaQuantum XT
SeaQuantum XT is one of Jotun’s best antifouling technologies – Tailored to Trade™ and an integral part of HPS 2.0. SeaQuantum XT is Jotun’s newest SeaQuantum antifouling that delivers robust performance for high fouling intensity trades. SeaQuantum XT is based on our proven SeaQuantum silyl methacrylate technology. Enhanced with Jotun’s ActiCore™ technology, it combines a patented in-house binder system with an optimised high-performance biocide package. This technology is designed to deliver consistent, reliable protection against intensified fouling threats.SeaQuantum XT delivers an expected speed loss of just 1.0%*, contributing to fuel savings of up to 14.7% and a corresponding reduction in carbon emissions. SeaQuantum XT delivers robust performance for high fouling intensity trades with a consistent 50 days idle period ability, and contributes towards decarbonization, protecting biodiversity and reducing fuel consumption by keeping the hull free from fouling. *Average in-service speed deviation over 60 months docking interval based on ISO 19030 measurement methods. Fuel saving estimates are compared with market average speed loss of 5.9% and a 1:3 power to speed ratio.
