7419 18 MM X 33 M

The 7419 18 MM X 33 M from 3M is a low static, non-silicone polyimide film tape. This tape with DuPont™ Kapton® polyimide film and acrylic adhesive is amber-coloured and used for PCB solder masking and other high temperature applications. 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 10min at 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. It is used for masking or protecting residue sensitive areas on printed circuit boards during high temperature operations such as wave soldering and solder reflow.
