• Reduce structure-borne noise in metal and
composite panels and support structures
• Optimized acrylic converts vibrational energy to
negligible heat that readily dissipates
• Reduce vibrational fatigue to decrease wear and
tear on parts and lower the risk of part loosening
and displacement
• Effective damping with as little as 10%
surface coverage
• Pressure sensitive for easy self-fi xturing application
• Long aging performance
• Good performance over a wide temperature range
• Linered construction provides ability to

Converting 3M Foil Tape Technologies
to the form and fi t you need for applications success
3M Converters match 3M™ Foil Tapes to
customer requirements with the exact form,
fi t, and functionality. Converter expertise
includes part design, quick prototyping,
slitting, and die-cutting. Applications range
from small, intricate copper foil EMI/RFI
shields for sensitive electronics to precisely
fi tted masks for commercial aircraft windows
during paint stripping.

Many 3M™ Metal Foil Tapes are linered for
easy handling and productive processing.
For example, General Purpose Aluminum
Foil Tape 3367 features a 66# moisture
stable liner for die-cutting. The 40# kraft
liner on General Purpose Aluminum Foil
Tape 3380 holds shape and position when
slit into narrow rolls.
With conformability and chemical resistance,
die-cut masks of 3M™ Aluminum Foil Tape
protect aircraft windows during harsh chemical
