PPG(NYSE: PPG) today announced the launch of PPG SIGMA SAILADVANCETM NX coating, which is the latest addition to the successful PPG Sigma Sailadvance range and a significant breakthrough in antifouling technology.
PPG Sigma Sailadvance NX coating was specifically developed to provide maximum hull protection and vessel performance in line with the requirements arising from International Maritime Organization(IMO) energy-efficiency measures. The coating delivers significant savings in fuel and related carbon dioxide(CO2) emissions, resulting in lower total operational costs and improved contribution toward global carbon-reduction measures.
The culmination of 10 years of intensive product development by PPG’s resin synthesis experts, PPG Sigma Sailadvance NX coating solves the shipping industry’s antifouling technology challenges by delivering real linear polishing, a minimal leached layer and protection against a broad spectrum of global fouling conditions. 
Formulated using PPG’s proprietary zinc methacrylate controlled surface active polymer(CSP) resin, PPG Sigma Sailadvance NX coating delivers ultra-premium performance with 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.
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 show no performance loss over the period of operation, with the coating reliably achieving 45 days of idle-time protection.
PPG Sigma Sailadvance NX coating also contains an ultra-strong biocide package that targets a wide range of global fouling growth conditions, from bacterial slime and soft fouling to aggressive animal fouling.
PPG’s ultra-premium zinc methacrylate CSP resin gives a molecular structure with twice as many reactive sites to promote chemical hydrolysis than other acrylate technologies. This allows hydrolysis to be carefully controlled and results in a minimal leached layer and true linear polishing. It also ensures that biocide availability is controlled to the level required for maximum and stable protection over the operational period and while stationary.
