Effective January 1, 2019, SIGMA will stock the newly NSF 61-approved Blackhawk R-17-A-73 aerosol coating/primer. The product is an ANSI/NSF61 approved, quick drying black asphalt glossy coating that can be universally used for the inside and outside of ductile iron pipes and fittings, including for potable applications. SIGMA is the only distributor in the US to carry this NSF 61-approved asphalt aerosol coating/primer.
The aerosol is especially useful for touchup and recoating of pipes and fittings and is applicable anywhere that asphalt is used to protect cast iron pipes and fittings. SIGMA’s National Customer Service Manager Craig Schapiro comments, “Previously, customers had to buy gallons of this paint in drums for small local applications. This new product is very versatile, convenient to use, and good to keep on hand. We had numerous waterworks industry customers call us and ask if they could use the paint in a potable setting. With this new NSF 61 approval, the aerosol can safely be used in this way”.
