Global coatings company PPG recently announced that the EDR Antwerp shipyard in Belgium has achieved a 40% reduction in overspray with the electrostatic application of one of the manufacturer's fouling release coatings.
The project was reportedly completed on the underwater hull of a RoRo passenger vessel Stena Transporter from Stena Line. PPG adds that this is the second successful electrostatic application project for the shipyard.
According to the press release, electrostatic application has increased transfer efficiency compared to airless spraying, resulting in reductions in overspray and waste.
PPG explains that, combined with the low VOC emissions of its Sigmaglide 2390 coating, this method provides cleaner operation and an improved work environment for the applicators. The chemical composition of both PPG Sigmaglide fouling release coating and PPG Nexeon 810 antifouling coating reportedly make them suitable for application using the electrostatic process.
“Electrostatic application increases the weather window in which painting activities can take place, as well reducing overspray significantly,” said Philippe Trouillard, Commercial Manager, EDR. “It’s impressive to see how the charged paint droplets are attracted to the vessel surface almost like a magnet.
“You only have to look at the dock floors at the end of the project to see how much paint has been saved from disappearing into the environment. Due to a cleaner operation, we have spent less time masking the vessel and covering the dock, saving valuable time and costs.”

“Ship owners and shipyards are being encouraged to look for innovative solutions in order to comply with stricter environmental regulations and meet their sustainability goals,” said Sijmen Visser, PPG Sales Director, Marine EMEA, Protective and Marine Coatings.
“We see an increased demand not only for biocide-free and copper-free hull coatings to reduce vessel emissions, but also for more sustainable application procedures by yards. We strongly believe in the sustainable concept of electrostatic application and are promoting the concept in shipyards in Europe, Singapore and China.”
Sigmaglide 2390 was released in March 2023 to help shipowners lower power consumption and carbon emissions. The biocide-free release coating is based on PPG’s HydroReset technology, which modifies the coating when it is immersed in water to create a super-smooth, almost friction-free surface that marine organisms do not recognize and cannot adhere to.
At the time, PPG reported that the coating results in up to a 35% reduction in CO2 emissions in comparison to traditional antifouling coatings, depending on ship model and operating conditions. In service, the coating can deliver up to 150 days of idle performance and an extended lifetime of more than 10 years with minimal maintenance requirements.
