| Description: BR® 6750 corrosion inhibiting primer is a one-part, chromate-based, modified epoxy primer which contains no volatile organic components (VOCs). BR 6750 is 100% water-based and does not rely on exempt solvents to achieve its zero VOC level rating. BR 6750 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 6750 also provides outstanding performance with most 350°F (177°C) curing adhesive systems. It offers wide application/processing latitude. It can be processed simply with HVLP or standard air atomizing spray equipment and is insensitive to spray booth conditions in temperatures from 65°F to 95°F (18°C to 35°C) and RH up to 65%. Features & Benefits : - No volatile organic components, 100% water-based, zero VOCs
- Promotes metal-to-metal adhesion
- Short drying time, easy to determine when flash-off is complete
- Drips and runs are less likely to occur, clean up requires only water
- Rated at 600 hours continuous operation, minimal spray gun clogging
- Excellent corrosion resistance, protects metals
- Mechanical properties equal to solvent-based primer systems with primer thickness from 0.00015 minimum to 0.0004 inch (0.0038 minimum to 0.010 mm)
- Can be cured from 250 – 350°F (121 – 177°C) and is compatible with a wide variety of 350°F (177°C) curing adhesives
- Service temperature from -70 – 350°F (-57 – 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 – 55°F (4.4 – 12.8°C)
