Low Static Polyimide Film Tape 7419
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.

Temperature use range is defined as the maximum time at the stated temperature after which the 3M tape 7419 may be removed cleanly,
without staining, from a copper substrate.
General Information
• Splice-free maximum roll length is 36.1 yd -0/+.2 yd (33 m -0/+2 m).
• Typical slit roll width tolerance: target ± .031 in (± 0.8 mm).
• Product provided on plastic polyethylene cores and individually packed.
Core ID = 3.020 in ± .004 in (76.7 mm ± 0.1 mm).
• Substrate should be smooth, clean, dry and oil-free to ensure good wet-out and adequate adhesion.
• Tape may not bond or conform to low surface energy, rough or sharply curved surfaces.
Storage and Shelf Life
To obtain best performance, use this product within 18 months from date of delivery and store under normal conditions
of 16° to 27°C (60° to 80°F) and 40 to 60% relative humidity in the original carton.
