PPG white paper examines electrostatic spray application for marine hull coatings
Last update on Jun 3, 2026
PPG has published a white paper titled Electrostatic Application of Marine Hull Coatings, examining the use of electrostatic spray technology in marine coating applications and its potential impact on coating efficiency, material use, and vessel performance.
According to PPG, electrostatic application involves applying a negative charge to paint particles at the spray gun nozzle while the substrate is grounded. The company states that the resulting attraction between the coating particles and the surface can improve transfer efficiency and reduce overspray compared with conventional spraying methods.

Reported 40% reduction in overspray
PPG stated that the process can produce a more uniform coating application. The company cited a case study from EDR Antwerp shipyard, which reported a 40% reduction in overspray following the use of electrostatic application technology.
“Electrostatic application is a breakthrough process innovation that, combined with our chemistry innovation, delivers improved productivity and sustainability for our shipyard customers,” said Jan Willem Tegelaar, global platform director, marine coatings at PPG. “It has already revolutionized the automotive and aerospace industries; building on this cross-industry expertise, we have adapted the technology and developed compatible fouling control coatings to save time and reduce waste without disrupting existing workflows for marine vessels.”
According to PPG, reduced paint consumption associated with electrostatic application may contribute to lower material use throughout the coating lifecycle, including raw material extraction, manufacturing, and transportation. The company also stated that these potential reductions are in addition to operational carbon savings associated with low-friction hull coating technologies that may help vessel operators reduce Scope 1 emissions.
“Electrostatic application is just one piece of the puzzle. Combined with advanced hull coating performance, it contributes to a more effective sustainability solution,” said Joanna van Helmond, product development director, marine fouling control, Protective and Marine Coatings at PPG. “Friction caused by biofouling can account for 50% of a ship’s total drag, leading to higher fuel consumption. By applying solutions such as PPG SIGMAGLIDE® 2390 coating electrostatically, we can create a smoother, glossier film that reduces hydrodynamic resistance. This in turn leads to lower fuel consumption and greenhouse gas (GHG) emissions.”
According to PPG, the white paper covers:
The development and operating principles of electrostatic spray technology.
Operational considerations associated with electrostatic application for shipyards and vessel owners.
The role of hull coatings in supporting vessel efficiency and the International Maritime Organization's (IMO) decarbonization objectives.
PPG also announced that it plans to present its approach to marine coatings, including low-friction hull coatings, electrostatic application technologies, and digital tools, at the Posidonia International Shipping Exhibition.
