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

BR® 6747-1 corrosion inhibiting primer is a one part, chromate based, modified epoxy primer which contains no volatile organic components (VOC).

BR® 6747-1 is 100% water-based and does not rely on exempt solvents to achieve its zero VOC level rating. It exceeds all state and federal VOC emission regulations for structural adhesive bonding primers and offers mechanical properties and corrosion resistance equal to that of solvent-based primer systems. In addition, BR® 6747-1 also provides outstanding performance with most 250ºF - 350ºF (121ºC - 177ºC) curing adhesive systems.

BR® 6747-1 offers wide application/processing latitude, simple processing with High Volume Low Pressure (HVLP) or standard air atomizing spray equipment and is insensitive to spray booth conditions - temperature from 65ºF - 90ºF (18ºC - 32ºC) and relative humidity from 30% - 70%. For applications which do not allow the use of chromate corrosion inhibitors, please see the Technical Datasheet for BR® 6747-1 NC non-chromate-based corrosion inhibiting adhesive bonding primer.
