-40ºF to +176ºF (-40ºC to +80ºC)

Image Enhancement:
Use of B-680 on BradyJet™ media printed with Brady's pigmented inks shows up to 25% increase in absolute color density as measured by Macbeth® ColorChecker® RD-1255.

Accelerated Weathering (SAE J 1960):
BradyJet™ vinyl (B-665/B-676) printed with Brady's pigmented inks and laminated with B-680 exhibits no change in density for cyan, magenta and black, and a maximum 8% loss for yellow over 1740 hours in weatherometer.

Water Resistance:
Graphics on BradyJet™ vinyl (B-665/B-676) printed with Brady's pigmented inks and laminated with BradyJet™ B-680 overlam will not bleed with water submersion up to 30 days. The system may show some white stain at the edges after heavy water exposure. Drying eliminates the stain.

Aggressive Chemicals Resistance:
B-680 overlam film is resistant to most mild acids, alkalies, salt solutions and some organic solvents.
Shelf Life:
1 year when stored at 73°F (23°C) and 40% to 50% R.H.
