Technical Data Sheet

3M™ Adhesive Transfer Tape 966
Product Description
The 3M™ Adhesive Transfer Tapes with 3M™ High Temperature Acrylic 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.
Product Features
3M™ Adhesive Transfer Tapes 941, 966, 9461P, 9461PC and 9462P use the same 3M™ High Temperature Acrylic Adhesive 100 and come with different liners for a variety
of die cutting applications. 3M™ Adhesive Transfer Tape 965 uses a slightly modified 3M™ High Temperature Acrylic Adhesive 100 to provide excellent resistance to jet
fuel and other chemicals for identification labels on aircraft.
• Excellent bond to metal and high surface energy plastics.
• Outstanding temperature and chemical resistance.
• Two adhesive thicknesses: 1 mil for thin profile labels and 2 mil for rougher surfaces.
• Low outgassing and low leachable chloride, important considerations for electronic and aerospace industries.
• Available on various liners for specialized processing:
– 62# Densified Kraft for die-cutting metal nameplates
– 55# Densified Kraft for rotary die-cutting specialty labels
– 58# Polycoated Kraft for moisture stability

Typical Environmental Performance
Chemical and Environmental Exposure The 3M™ High Temperature Acrylic Adhesive 100
is well known in industry for environmental and
chemical resistance. For many applications, any
one of the products in this grouping will perform
satisfactorily when exposed to different chemicals
or temperatures. Jet fuels, however, are a

challenge for pressure sensitive products. More
specifically, the Aviation Turbine Fuel, Grade JP-4
(MIL H-T-5624), will attack many of the best
adhesives within 72 hours. In response to the
demands of this market and the corresponding
military specification MIL-T- 9906C, 3M™
Adhesive Transfer Tape 965 was developed as it
differs slightly in chemistry from the rest of the 3M
adhesive 100 family to provide the extra chemical
resistance.
-
In addition to the added fuel resistance, 3M tape
965 retains all of the notable features of the
adhesive 100: excellent adhesion to metals, good
adhesion to high surface energy plastics, low
outgassing, and excellent static shear values for
room temperature and heated conditions. The
chart below shows adhesion values (to stainless
steel) of 3M™ Adhesive Transfer Tapes 965 and
966, with an emphasis on fuel and oil exposure.
The data represents representative or typical
values and should not be used for specification
purposes.
Environmental Resistance 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 Resistance:
Bond strength generally increases after cycling
four times 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 Service: -40°F (-40°C). Parts
should be tested for low temperature shock
service.
Storage and Shelf Life
Humidity controlled storage 60°F (16°C) to 80°F (27°C) and 40 to 60% R.H. and in a plastic bag.
If stored properly, product retains its performance and properties for 24 months from date of manufacture.
Recognition/Certification
TSCA: These products are defined as articles under the Toxic Substances Control Act and therefore, are exempt from inventory listing requirements. Additional regulatory
information for IATD products is available on the regs website: www.3m.com/regs.
MSDS: 3M has not prepared a MSDS for these products which are not subject to the MSDS requirements of the Occupational Safety and Health Administration’s Hazard
Communication Standard, 29 C.F.R. 1910.1200(b)(6)(v). When used under reasonable conditions or in accordance with the 3M directions for use, the products should not
present a health and safety hazard. However, use or processing of the products in a manner not in accordance with the directions for use may affect their performance and
present potential health and safety hazards.
UL: 3M™ Adhesive Transfer Tapes 941, 966 and 9462P have been recognized by Underwriters Laboratories Inc. under Standard UL 969 Marking and Labeling in File
MH26206. For more information on the UL Certification, please visit the website at http://www.3m.com/converter, select UL Recognized Materials, and then select the
specific product area.
Automotive Disclaimer
Select Automotive Applications: This product is an industrial product and has not been designed or tested for use in certain automotive applications, such as automotive
electric powertrain battery or high voltage applications, which may require the product to be manufactured in a IATF certified facility, meet a Ppk of 1.33 for all properties,
undergo an automotive production part approval process (PPAP), or fully adhere to automotive design or quality system requirements (e.g., IATF 16949 or VDA 6.3).

Handling/Application Information
Application Examples
Ideal tape application temperature range is 70°F to 100°F (21°C to 38°C) and application to surfaces at temperatures below 50°F (10°C) is not recommended for most
pressure sensitive adhesives because the adhesive becomes too firm to adhere readily. However, once properly applied, low temperature holding is satisfactory. For more
specific information, contact Customer Service at 1-800-223-7427.
The liner used for 3M™ Adhesive Transfer Tapes 9461P, 9461PC and 9462P is not intended to provide premium release characteristics. Testing is urged for applications
where liner release is critical. These products are not recommended for use with non-transferable facestocks such as 3M™ Label Material 8070, 8071 or 8074 because of
the potential for liner caused pre-destruct.
3M™ Adhesive Transfer Tape 965 has been specially modified to provide outstanding performance for fuel line identification labels, bar code labels for harsh environments
and specially performance-engineered labels for automotive, aerospace and industrial markets. It also meets MIL-T-9906C specification requirements.
Application Techniques
For maximum bond strength the surface should be thoroughly cleaned and dried. Typical cleaning solvents are heptane or isopropyl alcohol.*
Bond strength can also be improved with firm application pressure and moderate heat, from 100°F (38°C) to 130°F (54°C), causing the adhesive to develop intimate contact

with the bonding surface.
*Note: Carefully read and follow the manufacturer’s precautions and directions for use when working with solvents. These cleaning recommendations may not be compliant
with the rules of certain Air Quality Management Districts in California; consult applicable rules before use.
