Hempel Launches New Coatings

Hempel is launching two new antifouling coatings, Globic 9500M and Globic 9500S.
 
According to the manufacturer, the coatings offer customers a potential 2.5% reduction in speed loss, meaning a significant fuel savings and lower CO2 emissions improving the operational efficiency of a vessel and minimising the operator's environmental footprint.
 
This coating series builds on Hempel's  Globic technology to deliver superior antifouling performance for new buildings and dry-dockings, delivering an outstanding return on investment and flexibility from outfitting through the entire docking interval.
 
Hempel's patented Nano acrylate technology is the strength behind the Globic range and provides a fine polishing control mechanism to bring the integral biocides to the surface at a stable rate ensuring a clean hull. By combining the strongest binder and biocide package for premium performance at different trading speeds, Globic 9500M and Globic 9500S outperform other self-polishing coatings (SPC) particularly when slow steaming.
 
Additionally, the patented microfibres incorporated in the paint give Globic 9500M and Globic 9500S a best in class mechanical strength to avoid cracking and peeling. Globic's unique technology allows it to start working as soon as the hull meets the water for full and immediate antifouling protection, making it highly efficient even for slow steaming and long idle periods.
 
Globic 9500 Series at a glance:
  • Lasting protection against all kinds of fouling – designed for 60+ months docking intervals
  • Suitable for all vessels at all speeds
  • Incorporates proven patented Nano acrylate technology
  • Patented microfibres for best-in-class mechanical strength to avoid cracking and peeling
  • Outperforms other SPC, particularly during slow steaming
  • Excellent colour stability

Nano acrylate technology
The new coatings incorporate specially designed water-activated Nano acrylate technology that uses nano capsules to control polishing. When seawater comes into contact with the nano capsules, it penetrates the hydrophobic outer shell. The hydrophilic inner core chemically hydrolyses and then expands which breaks through the outer shell, enabling controlled polishing. Consistent self-polishing and a constantly thin leach layer ensure uniform biocide release over the entire docking interval. Unlike other premium antifouling technologies, Nano acrylate technology provides immediate antifouling protection without the need for water friction.
 
Special microfibres reinforce the binder, providing a skeleton effect that gives the coating enhanced mechanical strength and makes it more resistant to cracking.
