When it comes to protecting the hulls of ice-going vessels, the glassflake reinforced surface treated composite (STC) Ecospeed has proven to be remarkably durable, typically outperforming many specialized ice class paints. The fact that the coating is non-toxic is also particularly important for ice trading vessels where toxic AF coatings are rapidly scraped off and deposit their toxic ingredients in what are often particularly sensitive environments.
Icebreakers and ships that trade in icy waters have their own very specific problems when it comes to protecting their underwater hull. Icebreakers have to use their weight to ram into thick ice and force a passage. Ice going ships, such as those trading in the North Baltic, the northern coasts of North America, the Great Lakes, and so on, are constantly being hit by chunks of ice which may be 50 centimeters or more in thickness. Not only is the ice highly abrasive, there is the additional factor that the steel of the hull flexes under the impact.
Ecospeed demonstrates excellent attachment to the hull and successful resistance to extremely icy conditions. For over seven years a number of vessels coated with Ecospeed have been sailing the most northern parts of the Baltic Sea during the winter season and as far as both the North and the South Pole. Despite this, there has been neither damage from the ice nor any deterioration of the coating and none of these vessels have required more than just a few touch-ups during their drydock visits.
