the latest member in our range of coating systems is Ecolast. This product is UltraViolet (UV) resistant and preserves its color while at the same time offering the corrosion and abrasion protection our coatings are known for.

Regular coatings will quickly lose their original color when exposed to the ultraviolet radiation present in sunlight. This is problematic when colorfastness is required, as is the case in for example offshore wind farms.

Upper hull of tug Helios coated with Ecolast

The upper part of this Alfons Håkans ice class tug boat was coated with Ecolast to preserve the color while also giving the hull full ice protection.

The bottom part of the tower of wind turbines are all coated in the same regulation yellow. It is essential that the coating used does not change color. In most cases an extra layer of polyurethane is applied to preserve the color. This additional layer is however not abrasive resistant and rapidly deteriorates, exposing the underlying epoxy which can be damaged down to bare steel. This then requires expensive offshore repair. A permanent and less cumbersome solution is therefore needed. Enter Ecolast.

Ecolast is highly resistant against salt, ultraviolet radiation, waves or even ice. Mechanical damage to the coated surface is minimized. This is especially important for (semi-) submerged structures such as wind turbines that are located in splash or tidal zones.

Ecolast will keep its color because it is highly ultraviolet resistant. Like all other coatings systems in the Subsea Industries family, Ecolast is also unaffected by corrosion. As a result no repaint is required once the coating has been applied, safeguarding the color and the integrity of the structure or vessel.

Application of Ecolast is done in two or more homogenous coats, each 500 µm DFT, with no need for primer or any additional coat. This makes the application very fast and easy to adapt to the schedule of a yard. The use of Ecolast can save months in the paint shop for a large wind farm project.
