PPG SIGMAGLIDE 2390 marine coating receives prestigious green chemistry award from the American Chemical Society

Key Terms

biocide-free technical

A biocide-free product or formulation does not contain chemicals designed to kill or control living organisms such as bacteria, fungi or insects. For investors, this matters because it can signal lower regulatory risk and appeal to health- and eco-conscious consumers, but it may also require alternative preservation or pest-control methods that affect cost, shelf life and liability exposure — similar to choosing preservative-free food in place of a version with preservatives.

fouling release technology technical

A coating or surface treatment applied to ship hulls and submerged structures that prevents marine organisms like barnacles and algae from sticking firmly, so they can be removed easily by water flow or light cleaning. Think of it like a nonstick pan for boats: by reducing the buildup that slows vessels and increases drag, it affects fuel use, maintenance cycles and compliance costs, which matter to investors tracking operating expenses and asset efficiency.

hydrodynamic drag technical

Hydrodynamic drag is the force that resists an object’s motion through a liquid, caused by fluid flow around the object’s shape and surface. It matters to investors because drag affects fuel consumption, speed, operating costs and efficiency for ships, offshore platforms, turbines and subsea equipment—so changes in design, maintenance or operating conditions can influence revenue, margins and capital spending. Think of it as the wet equivalent of wind resistance that makes moving through water harder.

greenhouse gas emissions technical

Greenhouse gas emissions are the gases a company releases into the air—like carbon dioxide or methane—that trap heat in the atmosphere and contribute to global warming. For investors, these emissions matter because they can lead to higher regulatory costs, fines, shifting consumer preferences, and physical risks (like supply-chain disruptions), or create opportunities in low-carbon products; think of emissions as a company’s climate footprint that can affect future profits and value.

iso 19030 technical

An international technical standard that defines methods for measuring changes in a ship’s hull and propeller performance and the resulting effects on fuel consumption and efficiency. It provides consistent procedures and metrics—like a reliable fuel-economy test for cars—so companies can quantify how fouling, wear, repairs or modifications change a vessel’s operating performance. Investors use it to compare efficiency, forecast fuel costs, assess maintenance impact and evaluate environmental performance across shipping assets.

Applicators electrostatically apply PPG SIGMAGLIDE® 2390 marine coating to a vessel hull. The biocide-free fouling release technology helps improve vessel efficiency and reduce emissions.

The ACS Green Chemistry Challenge Awards recognize technologies that advance sustainability through innovative chemistry and deliver environmental, economic and performance benefits.

“This recognition from ACS underscores the role innovative solutions can play in addressing complex sustainability challenges,” said David Bem, PPG senior vice president, science and technology, and chief technology officer. “With PPG Sigmaglide 2390 coating, our scientists took a fundamentally different approach to marine fouling control, designing a solution that eliminates the need for biocides while delivering significant performance benefits. The coating is also suitable for electrostatic application, a method PPG introduced to the marine industry that helps reduce overspray and waste during dry dock applications. This award recognizes how material design can help address environmental challenges at their source."

Marine biofouling on vessel hulls increases hydrodynamic drag, resulting in higher fuel consumption and greenhouse gas emissions.

PPG Sigmaglide 2390 coating incorporates PPG HYDRORESET™ technology, which senses the presence of water and reorganizes the coating surface at the nanoscale to create an ultrasmooth, ultra low-friction interface. Marine organisms do not recognize the surface as a suitable substrate for permanent attachment and are more readily released during vessel movement.

Third party evidence following ISO 19030 and the International Towing Tank Conference standards demonstrates that the coating can provide potential power savings of up to 20% and potential reductions in CO₂ emissions of up to 35%, with actual performance depending on vessel type and operating conditions.

“The marine industry is increasingly focused on solutions that improve operational efficiency while reducing environmental impact,” said Amy Ericson, PPG senior vice president, Protective and Marine Coatings. "PPG Sigmaglide 2390 coating demonstrates that ship owners and operators do not have to choose between sustainability and performance. By helping reduce drag without relying on antifoulants, the technology delivers meaningful value for our customers while helping protect the marine environments in which they operate.”

The award reflects PPG's commitment to developing innovative, sustainably advantaged solutions that solve customers’ biggest challenges. Through technologies such as the PPG Sigmaglide 2390 coating, PPG combines high performance with responsible chemistry to help customers improve operational efficiency, reduce environmental impacts, and advance their decarbonization goals.
