PPG Industries’ protective and marine coatings business offers a range of copper-free marine coatings formulated to help protect commercial ships from fouling and discoloration during the building process and while in service. Sigma Nexeon coatings are designed to protect the vessels’ underwater hulls while stationary in seawater so as to minimize cleaning costs before delivery to the field. This also helps reduce the environmental impact without compromising on operational efficiency, the company says.
The absence of copper in the coatings makes their application smooth, resulting in improved ship fuel efficiency. This also means the coatings do not produce a “'whitening” effect when applied.
Sigma Nexeon 710 is an antifouling solution for operational vessels and is applicable at the time of construction and dry docking. Sigma Nexeon 750 is a high-activity, copper-free antifouling topcoat for new-builds in which outfitting takes longer than six months.
