Product Description
3M™ Low Static, Non-Silicone Polyimide Film Tape 7419 with DuPont™ Kapton® polyimide film and acrylic adhesive is
amber-colored and used for PCB solder masking and other high temperature applications.
Features and Benefits
Specially formulated acrylic adhesive is resistant to typical solder mask temperatures for short periods of time.
Stays firmly in place during processing and removes cleanly from typical electronic substrates even after 10 min
@ 260°C (500°F).
Non-silicone adhesive formulation lessens the potential for silicone contamination which can interfere with
subsequent bonding or conformal coating operations.
The high temperature acrylic adhesive also has excellent chemical resistance and should be considered for
demanding chemical masking applications.
• Product is wound on a polyethylene tape core.
