3M™ Electrical Tape 2131 is manufactured by coating a specially formulated and highly crosslinked silicone adhesive on a high temperature resistant polyimide backing film. It is typically used in electronic related applications to protect specific areas of a PCB during the wave soldering process.

FEATURES:

• 1-mil Polyimide backing.
• Silicone adhesive.
• Excellent adhesion to most substrates, even at high temperature.
• Very high cohesion strength.
• High heat resistance up to a maximum temperature of 260°C.

APPLICATIONS:

• Mask for protection of printed circuit board gold fingers during wave soldering or solder dipping process
