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 250ºF (121ºC) film adhesives and has been designed to provide optimal structural performance at temperatures ranging from -67ºF to 300ºF (-55ºC to 149ºC). 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 180ºF (82ºC) to 30 minutes at 250ºF (121ºC).

BR® 127 NC corrosion inhibiting primer is the non-chromated version of our standard BR® 127 corrosion inhibiting primer.

BR® 127 NC can be used with essentially all 250ºF (121ºC) epoxy-based film adhesives and has been designed to provide optimal structural performance at temperatures ranging from -67ºF to 300ºF (-55ºC to 149ºC). BR® 127 NC has favorable durability and corrosion resistance within the bond line, and can effectively be used as a protective coating outside bonded areas.

Recommended use with FM® 73, FM® 87, FM® 94, BR® 95, FM® 123-2, FM® 123-5, FM® 300, FM® 300-1, or FM® 300-2
