3M™ Adhesive Transfer Tapes 941, 966, 9461P, 9461PC and 9462P use the same 3M
adhesive 100 and come with different liners for a variety of die cutting applications.
3M™ Adhesive Transfer Tape 965 uses a slightly modified 3M adhesive 100 to provide
excellent resistance to jet fuel and other chemicals for identification lables on aircraft.

Product Description

These 3M™ Adhesive Transfer Tapes with 3M™ Adhesive 100 are designed for
temperature exposure to 450°F (232°C) for short periods of time and/or solvent
resistance. They have exceptional shear values even at elevated temperatures. They
also offer low “outgassing” properties, which is an important consideration for the
aerospace, automotive and electronic industries.

*Note: The caliper listed is based on a calculation from manufacturing controlled adhesive coat

weights using a density of 1.012 g/cc. While past data pages have listed nominal thicknesses
of 1 mil and 2 mils, the coat weight (and theoretical caliper) has not changed.

Environmental
Performance

The properties defined are based on the attachment of impervious faceplate materials
(such as aluminum) to an aluminum test surface.

Bond Build-up: The bond strength of 3M™ Adhesive 100 increases as a

function of time and temperature.

Humidity Resistance: High humidity has a minimal effect on adhesive

performance. Bond strengths are generally higher after
exposure for 7 days at 90°F (32°C) and 90% relative
humidity.

U.V. Resistance: When properly applied, nameplates and decorative trim

parts are not adversely affected by outdoor exposure.

Water Resistance: Immersion in water has no appreciable effect on the bond

strength. After 100 hours in room temperature, the bond
actually shows an increase in strength.

Temperature Cycling Bond strength generally increases after cycling four times
Resistance: through: 4 hours at 158°F (70°C)

4 hours at -20°F (-29°C)
16 hours at room temperature

Chemical Resistance: When properly applied, nameplate and decorative trim

parts will hold securely after exposure to numerous
chemicals including gasoline, oil, Freon™ TF, sodium
chloride solution, mild acids and alkalis.

Heat Resistance: The 3M adhesive 100 is usable for short periods (minutes,

hours) at temperatures up to 450°F (232°C) and for longer
periods (days, weeks) up to 300°F (149°C).

Low Temperature -40°F (-40°C). Parts should be tested for low temperature
Service: shock service.
