Kansas City, Kansas - VersaFlex Inc. says its polyurea systems for potable water applications have received the highest level of US National Sanitation Foundation approval for use in the polyurea industry.
The Kansas-based polyurea specialist said its AquaVers line of pure polyurea systems qualified as a interior/lining barrier system for tanks, vessels, storage containers and pipes that are used for drinking water under the NSF/ANSI standard 61 Section 5.
The standard establishes minimum health effect requirements for materials or components that contact drinking water, VersaFlex said. Section 5 of the standard covers specific requirements for protective barrier materials, such as sealants, coatings and paints.
VersaFlex's AquaVers line includes an aromatic system (AquaVers 405), an aliphatic system (AquaVers 201) and an aromatic structural system (Aquavers 415). The systems qualified with and without the CrobeFlex antimicrobial additive. The company added that its AquaVers 20 primer may also be used in conjunction with coatings.
