VersaFlex has been certified by Truesdail Laboratories, Inc. to meet NSF/ANSI Standard 61 Section 5 specifications for potable water.
VersaFlex’s AquaVers™ Line of Pure Polyurea Systems for Potable Water Application qualified as a Polyurea Interior/Lining Barrier System for Tanks, Vessels, Storage Containers and Pipes that are used for Potable/Drinking Water. The AquaVers™ product line includes our aromatic system (AquaVers 405) an aliphatic system (AquaVers 201) and the aromatic structural system (AquaVers 415). These polyurea systems qualified with and without the CrobeFlex® anti-microbial additive. AquaVers 20 Primer may also be used in conjunction with the coatings and is also certified by Truesdail as meeting NSF/ANSI 61.5 specifications as well.
The VersaFlex AquaVers Polyurea Systems not only qualified to meet the requirements of the standard in cold water use (23° C, or 73.4° F), but the the AquaVers 201 and Aquavers 405 were also tested and qualified for Potable Water Usage in high temperature applications up to 60 +/- 2° C (140° F). This makes VersaFlex’s AquaVers the only polyurea coating and liner system qualified for potable water application up to this higher temperature limit.
Not only does AquaVers meet a broad range of temperature approvals under NSF/ANSI standards, the VersaFlex coating systems also have a superior rating for minimum vessel (tank) size and no limits on the maximum thickness the coating may be applied. For the AquaVers 201, minimal tank size is 50 gallons; for the Aquavers 405, minimal tank size is 1,000 gallons; and the AquaVers 415 (23° C / 73.4° F only), minimal tank size is 5,000 gallons.
This is a very unique advantage to the VersaFlex Potable Water Coating Technology since most other NSF/ANSI 61.5 approved polyurea materials are restricted as to minimum tank size to be lined, as well as maximum thickness the material can be applied.
