Technical Data Sheet
BRADY B-702 FLEXIBLE FILM TAPE
TDS No. B-702
Effective Date: 12/09/1999
Description:
Brady B-702 is a flexible film tape with a white vinyl topcoat and a high tack rubber-based pressure sensitive adhesive.
Bray B-702 is an excellent wiremarker material for applications requiring good resistance to solvents and oils. It is an ideal marker for machine tool applications.
Brady B-702 has excellent flexibility, which makes it suitable for wrapping on thin gauge wire. The tape also has low profile when wrapped on wires.

CHEMICAL RESISTANCE
Pre-printed B-702 wiremarker samples were wrapped on 0.080" OD wires and unprinted samples were laminated to aluminum panels. Samples 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.
