Antifouling Coating · Paint & Coating Systems
Hull and tank protection coatings are essential for maintaining the structural integrity and efficiency of maritime vessels. Hempel A/S offers a range of high-performance coatings under the designations Hempaprime Uni 720, 17850, Hempatop Tough 500, 55800, which are IMO-approved and designed to meet stringent marine standards. These coatings include epoxy primers and intermediate layers (Hempadur), silicon-hydrogel hull coatings for fuel efficiency (Hempaguard), and antifouling coatings with nano-acrylate technology (Globic). The Hempaprime Uni 720, 17850, Hempatop Tough 500, 55800 systems are specified to achieve a dry film thickness of 320 µm for epoxy layers and 100 µm for antifouling, ensuring robust protection against corrosion and fouling. Proper surface preparation is critical; the coatings require a Sa 2.5 ISO 8501-1 surface roughness, verified with Rugotest No. 3 or an ISO Rau-Mittel (G) comparator. Common issues such as insufficient surface roughness, salt contamination, and inadequate dry film thickness can lead to coating failures. Regular inspections at docking intervals are recommended, along with immediate touch-up work on any damage. Anode checks every six months and antifouling renewal every five years are essential for maintaining optimal performance of the Hempaprime Uni 720, 17850, Hempatop Tough 500, 55800 systems.
