New Product Announcement: Antifouling Technology


Global coatings company PPG recently announced the launch of a new antifoulant coating: PPG Sigma Sailadvance NX. The new coating is the company’s latest addition its Sigma Sailadvance range and collection of antifouling technology.

According to PPG, the coating was developed to provide maximum hull protection and vessel performance in line with the requirements arising from International Maritime Organization (IMO) energy-efficiency measures.

Sigma Sailadvance NX is reported to offer cost savings in both fuel and related carbon dioxide emissions, which has also been shown to attribute to lower total operational costs and improved contribution toward global carbon-reduction measures. Specifically, the coating reports a minimal speed loss of 1.0% to 1.5% on average over the operational period as well as improved fuel-saving capabilities and up to 15% CO2 savings.

“In developing PPG Sigma Sailadvance NX coating, our goal was to overcome the major challenges of antifouling technologies with a unique binder that ensures constant biocide availability on the hull surface and protection against broad fouling conditions,” said Ariana Psomas, PPG Global Segment Director, Newbuild and Dry Dock, Protective and Marine Coatings.

“The new antifouling technology delivers significant CO2 savings during operation and guaranteed long-term static protection, making it an effective solution to meet emerging industry needs.”

The company went on to report in its announcement that the coating was formulated using PPG’s proprietary zinc methacrylate-controlled surface-active polymer (CSP) resin. In addition, the coating uses a binder formulation that provides real linear polishing that is unaffected by changing seawater temperatures and minimizes the development of a leached layer.

Tests and applications with existing customers were reported to show no performance loss over the period of operation, achieving 45 days of idle-time protection.

“Thanks to the combination of its three unique levers, PPG Sigma Sailadvance NX coating far exceeds the performance delivered by products that are based on other acrylate technologies,” Psomas concluded.
