Hempel Tin-Free Self-Polishing Antifouling Dynamic 9000 79950 is an antifouling coating. It is suitable for newbuildings and for maintenance of underwater hulls and the waterline area, with dry-docking intervals of up to 90 months. The product contains a higher concentration of advanced biocides, preventing fouling under severe sailing conditions over longer dry-docking intervals, substantially reducing speed loss after prolonged service and ensuring a high fuel-saving potential. Parameters on this page: volume solids 58 ± 2%, dry film thickness 100 µm, theoretical spreading rate 5.8 m²/L.

Hempel Tin-Free Self-Polishing Antifouling is a high-quality high-solids chemically hydrolysing silyl acrylate antifouling coating. The product exhibits extremely low friction and predictable polishing performance, with an extremely short activation time, ranking among the foremost products of its antifouling class. The product contains a higher concentration of advanced biocides, preventing fouling under severe sailing conditions over longer dry-docking intervals, substantially reducing speed loss after prolonged service and ensuring a high fuel-saving potential. Hempel Tin-Free Self-Polishing Antifouling employs Hempel microfibre technology, providing excellent mechanical strength and effectively avoiding cracking and flaking.
This product contains no organotin compounds as biocides, and complies with the International Convention on the Control of Harmful Anti-fouling Systems on Ships adopted by the IMO in October 2001 (IMO document AFS/CONF/26).
Suitable for newbuildings and for maintenance of the underwater hull and waterline, with dry-docking intervals up to 90 months.
- Broad-spectrum biocides prevent hard and soft fouling. Low drag and smooth surface suitable for various sailing speeds. High solids content for fast application, reducing dry-docking time. Easy to apply. Flexible application, suitable for warm and cold environments (below 0 °C).
