New Cobalt-Free AOC Resin Has Earned Certification by NSF International

June, 2012: Collierville, TN

Certified to NSF/ANSI 61

New Vipel® F010-H2O-00 vinyl ester from AOC is certified to NSF/ANSI 61: Drinking Water System Components-Health Effects by NSF International, making it easier for customers to manufacture products for potable water applications. The resin's cobalt-free formulation also gives it superior corrosion resistance for applications that contain sodium hypochlorite, or bleach.

Benefits of NSF Certification

The NSF/ANSI 61 standard establishes health effects requirements for products, components, and materials used in drinking water systems. "Customers that fabricate products for drinking water use can be assured that this resin conforms to the health effects requirements for NSF 61," said Fletcher Lindberg, Business Manager for Open Mold, Reinforced Resins. "This makes it faster and easier for those companies to obtain NSF Certification for their products," said Lindberg. "The Vipel F010-H2O data sheet describes the protocols for customers to follow to meet the requirements," Lindberg added.

Benefits of Cobalt-Free

Vipel F010-H2O uses a special catalyst that does not require a cobalt promoter. This feature makes the coating suitable for sodium hypochlorite containment. In contrast, composite materials that use cobalt-based promotion weaken over time when exposed to bleach or sodium hypochlorite.

"Since F010-H2O is formulated for sodium hypochlorite resistance, the composite equipment lasts longer and saves customers the cost of replacement," explains Scott Lane, Corrosion Product Leader. "This is a tremendous benefit for customers in the municipal water treatment sector where the use of sodium hypochlorite as a sanitizer is increasing," Lane added.

How the new resin is used

Vipel F010-H2O is used as a coating system in tanks that hold at least 4,000 gallons (15,142 liters) and piping at least 6 inches (152 millimeters) in diameter. When the resin is formulated and processed according to specifications, the coating system is suitable for both potable water (as demonstrated by the NSF 61 certification), as well as sodium hypochlorite containment used in potable water systems.  

About NSF International

NSF International is an independent organization that writes standards, tests and certifies products for the food, water and consumer goods industries to minimize adverse health effects and protect the environment ( Founded in 1944, NSF is committed to protecting human health and safety worldwide. NSF is a World Health Organization Collaborating Centre for Food and Water Safety and Indoor Environment.

NSF International's Water Programs require extensive product testing and unannounced audits of production facilities to verify that water treatment products meet the design, material and performance requirements. NSF International is accredited by the American National Standards Institute (ANSI).

NSF led the development of the American National Standards for all chemicals used to treat drinking water and materials/products coming into contact with drinking water. In 1990, the U.S. EPA replaced its own drinking water product advisory program with these NSF standards.
