3M 7419 Low Static Polyimide Tape

3M™ Low Static, Non-Silicone Polyimide Film Tape 7419 is a 2.8 mil industrial grade tape product used for high temperature circuit board masking applications. This product features low levels of static discharge during the unwinding and removal of the product as well as a non-silicone alternative adhesive which suits applications necessitating a limitation of silicone contamination.

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 @ 500°F (260°C)
Non-silicone adhesive formulation eliminates the potential for silicone contamination which can interfere with subsequent bonding or conformal coating operations

Color: Amber

Backing/Carrier Material: DuPont™ Kapton® Polyimide Film

Adhesive Type: Acrylic

TotalThickness: 2.8 mil
