Technical Data Sheet

BRADY B-642 FILM TAPE

TDS No. B-642
Effective Date: 21-Feb-2000

Description:
Brady B-642 is a translucent polyvinylfluoride film with a primed printable surface and a permanent acrylic pressure sensitive adhesive.

Brady B-642 is typically used in a self-laminating format which has a white printable or write-on zone and a translucent overlaminating area. Brady Series 2000 and 5000 ribbons are recommended for dot matrix printing of B-642.

Brady B-642 has good print smudge resistance, solvent resistance, and elevated temperature performance. B-642 is a thin tape with excellent flexibility for wrapping on small diameter wires. The polyvinylfluoride film provides good self-extinguishing properties.

PERFORMANCE PROPERTY
SOLVENT RESISTANCE
B-642 self-laminate samples were printed with Series 2000 and 5000 ribbons, wrapped around 0.080" OD TFE jacketed wires, and dwelled 24 hours prior to test. Testing consisted of 5 cycles of 10 minute immersions in the specified chemicals followed by 30 minute recovery periods. Testing was conducted at room temperature.
