• Brand: 3M
• Item No.: 7419
• Backing: Polyimide Film
• Adhesive: Acrylic
• Color: Amber

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 can be considered for demanding chemical masking applications.
• Product is wound on a polyethylene tape core.

Masking or protecting residue-sensitive areas on printed circuit boards during high-temperature operations such as wave soldering and solder reflow
