Important Upcoming Changes to Regulations for Potable Water Linings
On January 1, 2023, NSF will implement a new health requirement called NSF/ANSI/CAN Std. 600 (NSF 600) which will require all coatings in contact with potable water to meet new, lower extraction levels. These new limits will severely restrict available product offerings from most coating and lining manufacturers and only coatings with extractables of xylene less than 0.09 mg/L, ethylbenzene less than 0.14 mg/L and toluene less than 0.06 mg/L, will be certified for use on potable water structures and components.
Tnemec Company is well-prepared for these changes and has already certified Series 22 Epoxoline, Series FC22 Epoxoline, Series 91-H20 Hydro-Zinc, Series 94-H20 Hydro-Zinc and Series 406 Elasto-Shield for NSF 600 requirements. In the coming months, Tnemec will also introduce innovative NSF 600-compliant formulations to further expand our customers' coating choices.
To learn more about NSF 600 and its effect on coating selection and specification, watch the video below and download our tech bulletin. Or, for further assistance, contact your local Tnemec representative.

Zinc-Rich Primers for Water Tank Interiors
Over 20,000 tanks have been coated with Hydro-Zinc since its introduction in 1997. The first organic zinc-rich primer to be NSF 61 certified for use in potable water immersion, Hydro-Zinc has demonstrated unparalleled long-term corrosion protection for both the interior and exterior of steel water tanks. It is compliant throughout North America with versions featuring low HAPs levels and less than 100 grams per liter VOCs and will continue to meet regulations through 2023 and beyond.
100% Solids Epoxy Linings for Potable Water
Series 22 & FC22 Epoxoline products are advanced generation, 100% solids, high-build epoxy linings built to protect steel and concrete tank interiors. These reliable, low VOC linings are suitable for immersion service in both potable water and wastewater environments, meeting the requirements of NSF 61 and 600. With quick cure capabilities, excellent abrasion resistance and a history of limiting corrosion in a variety of exposures, Epoxoline products offer long-lasting, thick-film protection to tank interiors.
Other Innovative Coatings for Tanks and Treatment
Tnemec is no stranger to innovative coatings for water tanks. In fact, our interior coating systems have always represented the most comprehensive NSF 61 selection in the industry and will continue to do so even as the industry changes. For specifications that require incredible longevity and protection for tank exteriors, Tnemec zinc-rich primer, polyurethane and fluoropolymer technologies have been considered the standard for the industry for decades. Many of our coating systems conform to the American Water Works Association (AWWA) D102 Standard for Painting Steel Water Storage Tanks and we offer products that meet every air quality regulation in North America.
