ST. PAUL, MN -- H.B. Fuller Co. has received notification from NSF International that its UR3501 A/B two-part adhesive for spiral wound membrane bonding for reverse osmosis (RO) filtration has been tested and certified by NSF to NSF/ANSI Standard 61 - Drinking Water System Components - Health Effects. This certification adds to H.B. Fuller's NSF certification of two of its potting compounds (FE7811 epoxy and UR2187 polyurethane) for hollow fiber water filtration. H.B. Fuller has been a leading supplier of spiral wound membrane bonding for RO for more than 20 years.
Using adhesives that carry the NSF certification mark brings H.B. Fuller's customers closer to achieving NSF certification for their finished filters. In some instances, manufacturers using NSF-certified materials can bypass some or all chemical testing when seeking NSF certification of their filter, providing assurance that their finished products meet all standards.
