Br127 Corrosion Inhibitor Primer
UN Number: UN1993 CL3 II
Limited Quantity: 1L
Hazardous for transport
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. 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). Articles primed with BR 127 primer and then cured have an indefinite shelf life. Primed details should be wrapped in Kraft paper (as protection from dust and dirt) and stored prior to adhesive bonding. Mainaining controlled conditions of 85°F (29°C) maximum temperature and 65% maximum humidity is recommended for ex ended 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.
