Important Upcoming Changes to Regulations for Potable Water Linings
On January 1, 2023, NSF will implement new extraction criteria for xylene, ethylbenzene and toluene. The extraction criteria found in the NSF/ANSI/CAN Std. 600 (NSF 600) reference standard 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.
NSF 600 Coatings with Years of Proven Performance in the Field
As a leader in the water tank industry, Tnemec is well-prepared for these changes, and has been anticipating potential rule and regulation changes like these for years. Our company has many full coating and lining systems that will still comply with the new NSF extraction criteria, including coating systems that have been applied to potable water tanks and piping for decades.
Series 22 Epoxoline: A 100% solids epoxy lining for potable water immersion introduced in 2001.
Series FC22 Epoxoline: Fast-cure, 100% solids epoxy lining built to protect steel and concrete surfaces, introduced in 2008.
Series 94-H20 Hydro-Zinc: A zinc-rich urethane primer applied on countless water tank interiors and exteriors that was introduced in 2003.
Series 91-H2O Hydro-Zinc: Standard zinc-rich urethane primer for water tanks used across North America since being introduced in 1997.
Series 406 Elasto-Shield: Polyurethane lining used on steel and concrete potable water structures, introduced in 2002.
Series N140 Pota-Pox Plus: Reliable epoxy coating certified for use as potable water primer, intermediate coat or stripe coat, introduced in 1999.
Series L140 Pota-Pox: Low VOC epoxy coating for potable water introduced in 2005.
At Tnemec Company, we constantly focus on protecting clean water infrastructure. That dedication spans the entire Tnemec family to include performance testing in the R&D laboratory, management involvement in water industry regulatory organizations, special attention given to packaging on the factory floor and continuous support and technical involvement with clients. With Tnemec, you can find no better informed and passionate advocate for your potable water coating needs.

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.
