Solvay BR® 6747-1 Bonding Primer
Categories: Polymer; Thermoset; Epoxy

Material Notes: 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. BR 6747-1 also provides outstanding performance with most 250 – 350°F (121 – 177°C) curing adhesive systems. BR 6747-1 offers wide application/processing latitude, simple processing with HVLP or standard air atomizing spray equipment and is insensitive to spray booth conditions at temperature from 65 – 95°F (18 – 35°C) and relative humidity from 30 – 70%.

Features & Benefits :

  • Zero V.O.C., 100% water-based
  • Short drying time, easy to determine when flash-off is complete
  • Drips and runs less likely to occur, clean-up requires water only
  • Spray gun clogging and tank scaling not an issue (rated at 600 hours continuous operation)
  • Excellent corrosion resistance
  • Can be cured from 250 – 350°F (121 – 177°C) and is compatible with a wide variety of 250 – 350°F (121 – 177°C) curing adhesives
  • Approved primer for AC-®130 bonding prep process (Boeing’s patented sol-gel technology)
  • Mechanical properties equal to solvent-based primer systems with primer thickness from 0.00015 to 0.0004 inches
  • Service temperature from -70°F to 350°F (-57°C to 177°C)
  • Protects prepared surface from further oxidation, prevents hydrolysis of oxide layers
  • MEK wipe resistant after 60 minute cure at 250°F (121°C)
  • Long storage life: 12 months at 40 – 50°F (4.5 – 12.8°C)
Suggested Applications:
  • Bond primer for aluminum components where corrosion protection is critical
  • Also very effective as a corrosion inhibiting paint primer for aluminium substrates.
  • Effective adhesion promoter for other metals (stainless steel, titanium, and nickel)
