BR 127

Product functions: Medium Service Temperature (70°C to 150°C)
BR® 127 corrosion inhibiting primer is a modified epoxy primer. It is the industry standard for high-performance corrosion inhibiting primers and has been used in virtually every commercial aircraft built since its introduction. BR® 127 primer can be used with essentially all 250°F (121°C) 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® 127 primer is formulated to provide maximum environmental resistance and durability within the bond line, as well as prevent corrosive undercutting. It can also be used effectively as a protective coating outside bonded areas. Solvay also offers BR-6700-1, a water-based, non-chromate adhesive bonding primer with similar characteristics.Type: primer | Temp: service temp < 320F | Process: autoclave, out of autoclave | Proc Temp: 180 - 250 (82 - 121) | Chromate: - | Water Based: N | Serv Temp: 300 (149)
