PPG Industries’ (NYSE:PPG) protective and marine coatings (PMC) business announced that four individual coatings and primers and two combined coating-and-primer systems have been certified by NSF International for water-tank applications. The new NSF certifications for PPG PMC products include the following:

· AMERCOAT(R) 133/844 pit-filler is a hand-applied coating designed to fill deep holes in pitted steel surfaces with a single pass. It features a 100-percent solids formulation and emits almost zero volatile organic compounds (VOCs), and it trowels easily to a smooth finish.

· SIGMAWELD(TM) 199 primer is a weldable preconstruction primer that provides up to 12 months of corrosion protection during construction and offers extended recoatability thereafter. Designed specifically for metal fabricators and plate-steel shops, SIGMAWELD 199 primer has a low-zinc, low-solids formulation that dries quickly, adheres strongly and applies easily to thicknesses of 1 to 1.5 mils in addition to providing a wide window for final coating system application

· NOVAGUARD(TM) 810 coating is a high-build, single-coat novolac-epoxy lining. With a solvent-free, 100-percent solids formulation, NOVAGUARD 810 coating cures rapidly and achieves 30-40 mil thickness in a single coat.

· Amercoat 68MCZ primer is a zinc-rich urethane primer for new construction and field-maintenance of water tanks. It is compatible with other organic and inorganic zinc primers and cures rapidly to enable accelerated topcoat application.

NSF International also certified PPG water-tank coating systems incorporating NOVAGUARD 810 coating over Amercoat 68MCZ primer and NOVAGUARD 810 coating over SIGMAWELD 199 primer.

Diane Kappas, PPG vice president, protective and marine coatings, Americas, said the NSF certifications enable PPG to expand its range of coatings solutions for water-tank builders, fabrication shops, subcontractors and maintenance personnel.

“PPG coatings and primers have a long history of proven performance in the water-tank field,” she explained. “The NSF stamp of approval makes it easier for customers to specify PPG products as a single-source solution and to choose a PPG coating system best suited to a particular application.”
