Product description

BR® 127 corrosion inhibiting primer is a modified epoxy primer. It is the industry standard for highperformance 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.
BR® 127 corrosion inhibiting primer can be cured prior to bonding. Recommended cure cycles range from 4 hours at 180°F (82°C) to 30 minutes at 250°F (121°C).
Primed details should be wrapped in Kraft paper (as protection from dust and dirt) and stored prior to adhesive bonding. Maintaining controlled conditions of 90°F (32°C) maximum temperature and 70% maximum humidity is recommended for extended storage life.
Cure cycles for adhesive films primed with BR® 127 primer may vary from 200°F to 350°F (93°C to 177°C) with minimum pressures to assure proper mating of bonded details.
