PPGIndustries Inc., Pittsburgh, offers a broad portfolio of marine coatings. Sigmashield 880, a surface-tolerant, abrasion-resistant epoxy, is commonly used in a single coat. Sigmashield 880 GF adds glass flake for improved resistance to cracking and sagging — ideal for workboat decks, according to the manufacturer. PSX 700, a low-VOC polysiloxane-epoxy hybrid, offers UV protection and abrasion resistance, making it suitable for high-exposure areas.
For antifouling, PPG’s ABC 3 is a self-polishing, organotin-free coating that helps reduce drag and meets IMO environmental standards. Nexeon 610 offers copper-free antifouling in a similar self-polishing formula. Sigmaglide 2390 is a biocide-free coating that uses Hy droReset technology to form a smooth surface resistant to marine growth. “It can deliver up to 35% emission reduction and enhance vessel energy efficiency,” said Josh Stinson, PPG commercial marine regional sales manager, protective and marine coatings.
PPG stands out in offering products like Sigmaglide and Nexeon that can be applied electrostatically — a process that directs charged paint particles to the grounded vessel surface, minimizing overspray and reducing waste.
For running gear, PPG offers Sigmashield 1200, developed for ice-going vessels. The reinforced, solvent-free epoxy phenolic coating combines anti corrosive properties with high polymer cross-link density to protect against gouging, abrasion and mechanical stress.
The newest addition to PPG’s Phen guard range, Phenguard 985, is a flexible coating that tolerates higher film thick nesses and can be applied in two or three coats, depending on the project.
