June 12, 2020 – PPG today announced that its PPG NOVAGUARD® 810ER coating has been qualified by the U.S. Naval Sea Systems Command (NAVSEA®) for use on potable water tanks. This qualification makes it the only coating that passes NAVSEA tests for six classes of tanks: fuel tanks, seawater ballast tanks, chemical holding tanks, bilges, well deck overheads, and potable or freshwater tanks.
“Having one coating qualified for all these tanks on a U.S. Navy ship has major advantages, including simplified ordering, fulfillment and materials management, for NAVSEA and its coating contractors,” said Juanjo Ardid, PPG vice president, protective and marine coatings, U.S. and Canada. “Tank fabrication and maintenance also can be streamlined and improved because contractors can use just one product.”
PPG NOVAGUARD 810ER coating is a single coat, direct-to-metal (DTM) novolac epoxy coating that easily builds to 20 to 30 mils without sagging. Unlike many existing tank coating technologies that require at least two coats, PPG NOVAGUARD 810ER coating provides one-coat coverage with excellent edge retention, saving time and labor and accelerating return to service. The coating’s high film build properties, wide application temperature range and ultra-high solids also make it applicator friendly.
PPG NOVAGUARD 810ER coating can easily be touched up with one-quart (0.9-liter) cartridges or 12-ounce (0.4-liter) “burst packs,” allowing tanks to pass stringent inspections. PPG AMERCOAT® 240 coatings are also available for touch-ups.
