BR® 179
NON-CHROMATE BONDING PRIMER
BR® 179 corrosion inhibiting primer is a non-chromate, one-part, modified epoxy bonding primer. This primer is designed to meet stringent requirements of adhesive bonding primers on various metallic substrates and is compatible with PAA, PSA, PSA/TSA, and Sol-Gel surface treatments.
BR® 179 can be used with essentially all 250°F (121°C) epoxy-based film adhesives and has been designed to provide optimal structural performance at temperatures ranging from -67°F to 300°F (-55°C to 149°C). BR® 179 has favorable durability and corrosion resistance within the bond line and can effectively be used as a protective coating outside bonded areas. BR® 179 also provides outstanding performance for most 350˚F (177˚C) curing structural adhesive systems.
BR® 179 has wide application and processing latitude, simple processing with HVLP or standard atomizing spray equipment and is insensitive to spray booth conditions – temperatures from 65˚F to 95˚F (18˚C to 35˚C) and relative humidity from 30% to 70%.
