NSF 600 Coatings & Linings

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.

Register for the upcoming continuing education webinar, "Changes to NSF Std 61 and AWWA D102: An Asset Management Based Approach to Coatings Selection" 

On Tuesday, October 18, at 1:00 p.m. central presenters, Randy Moore and Brian Cheshire will detail the upcoming changes in NSF/ANSI/CAN Std. 61 regulations in regards to potable water linings for water tanks and treatment infrastructure. This webinar will cover the changes in extractable criteria, the impact they will have on the industry, and the Tnemec products available now to meet these new regulations. 

AWWA recently published their D102-21 standard for potable water storage tank coating systems. Looking at this standard, how does a tank owner, or specifier, decide which of the 13 inside and outside coating systems to select for the protection of their storage tanks? Which system offers the longest service life and lowest life-cycle cost?

At the same time, asset management best practices also involve focusing on the lowest life cycle cost. In addition, sustainability goals involve obtaining the lowest service life possible at the lowest life-cycle cost.

This course will review these standards and will help provide answers to these questions so that owners, specifiers, and engineers can better understand how to select the right system for their projects. This course will also review upcoming changes to NSF/ANSI/CAN Std. 600 (which will take effect January 1, 2023) and how this will affect the coating and lining selection process for potable water tanks.

Innovative New Products Now Available for NSF 600 Requirements

Tnemec Company has introduced several coatings that will allow owners and engineers to update their water tank and treatment specifications with innovative, low VOC products. These coatings are formulated to perform as well as, if not better than, previous technologies, and will help prepare specifiers for the next phase of potable water protection.

Series 21 Epoxoline: A high-solids epoxy lining that can be used on the interior and exterior of steel or concrete tanks, pipes, valves, pumps, and other equipment in potable water service.

Series 1220 Tnemec Epoxy: A unique, low VOC, water-based epoxy coating featuring HydroLink technology, ideal for use in potable water tanks and water treatment facilities.

Series 98-H2O Hydro-Zinc: An innovative, waterborne zinc-rich epoxy primer offering extended protection on the interior and exterior of potable water storage tanks.
