VersaFlex Incorporated announces all of its specially formulated pure polyurea systems for potable water applications have achieved the highest level of NSF/ANSI 61 Section 5 (2011) approval in the polyurea industry.
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 the aromatic system (AquaVers 405) an aliphatic system (AquaVers 201) and the aromatic structural system (AquaVers 415). These polyurea systems qualified with and without their CrobeFlex anti-microbial additive. AquaVers 20 Primer may also be used in conjunction with the coatings.
NSF/ANSI Standard 61 Drinking Water System Components - Health Effects; is the standard that establishes minimum health effects requirements for materials, components, products or systems that contact drinking water, drinking water treatment chemicals or both. Section 5 of the Standard covers specific requirements for Protective Barrier Materials / Products such as sealers, coatings, paint, primer, mortar, Portland cements, cement ad-mixtures, etc.
The VersaFlex AquaVers Polyurea Systems not only qualified to meet the requirements of the standard in cold water use (23° C), 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, but 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 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.
The National Sanitation Foundation (NSF) International is an independent, not-for-profit organization that provides public health standards and certification that help protect the world's food, water, health and consumer products. Third-party certification means that an independent organization has reviewed the manufacturing process of a product and has independently determined that the final product complies with specific standards for safety, quality or performance. This review typically includes comprehensive formulation/material reviews, testing and facility inspections.
