 Marine coatings are another
common application for antimicrobials. When incorporated into paint or coatings
on the hulls of ships or on metal subsurfaces in a marine environment, antimicrobials
reduce or prevent biological deposits and biological corrosion.
A slime layer only 1 millimeter
thick on a hull can reduce the speed of a vessel by 15 percent and increase
fuel costs correspondingly.
Heavier deposits can also
result in corrosion of the metal itself and limit the life of the coating,
requiring premature dry-docking of the vessel.
