Hempel’s Globic 9500M and Globic 9500S incorporate water-activated Nano acrylate technology

Two antifouling coatings designed to offer a potential 2.5% reduction in speed loss have been launched.

Hempel’s Globic 9500M and Globic 9500S incorporate water-activated Nano acrylate technology which provides immediate antifouling protection without the need for water friction.

The speed loss reduction equates to fuel savings and lower CO2 emissions, improving the operational efficiency of a vessel and minimising the operator's environmental footprint, said Hempel.

Fouling protection

Henrik Dyrholm, global product manager at Hempel, said that Globic 9500M is designed for maintenance, “to protect against slime as well as soft and hard fouling in all conditions.”

He added that Globic 9500S is designed to manage static, “to protect against hard-fouling even during extended outfitting periods.”

Nano capsules

The Nano acrylate technology 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.

The technology starts working as soon as the hull of vessel meets the water, providing full and immediate antifouling protection, said Hempel. This makes it highly efficient even for slow steaming and long idle periods, it added.
