Product Data Sheet Updated : July 2000
Supersedes : December 1994
Physical Properties
Not for specification purposes Adhesive 5.0 thou (127 micron) #300LSE “Hi-Strength” Acrylic
Liner 4.0 thou (100 micron) 94g/m² 58# Polycoated Kraft
Shelf Life 24 months from date of manufacture when stored in
cartons at 70°F at 50% relative humidity.
Features: 300 LSE “Hi-Strength” Acrylic Adhesive provides very high bond strength to most
surfaces, including low surface energy plastics.
Extremely smooth, non-fibred adhesive for excellent graphic appearance.
Excellent bond to plastics and low surface energy coatings such as, polypropylene
and powder coated paints, combined with high shear for excellent temperature
resistance.
Excellent adhesion to surfaces contaminated lightly with oil typically used with
machine parts.
94 g/Polycoated Kraft liner for lay flat, moisture stability and excellent processing
of plastic graphic overlays.
Applications Plastic nameplates or graphic overlays for use on low surface energy plastics.
Waste removed nameplates on a common sheet for ease of application.
Graphic application to surfaces such as wood, fabric, plastic, where very high bond
strength is required.
Bonding a variety of foam substrates to metal and plastic surfaces.
Attaching identification material to oily surfaces typical of machine parts.

Properties and
Performance
(Not for specification purposes)
Bond Build Up The bond strength of #300LSE “Hi-Strength” Acrylic
Adhesive increases as a function of time and temperature,
and has very high initial adhesion.
Humidity Resistance High humidity has minimal effect on adhesive performance.
No significant reduction in bond strength is observed after
exposure for 7 days at 32°C and 90% relative humidity.
U.V. Resistance When properly applied, nameplates and decorative trim
parts are not adversely affected by exposure.
Water Resistance Immersion in water has no appreciable effect on the bond
strength. After 100 hours at room temperature, the high
bond strength is maintained.
Temperature Cycling
Resistance
High Bond strength is maintained after cycling four times
through:- 4 hours at 70ºC
4 hours at -29ºC
16 hours at 22ºC
Chemical Resistance When properly applied, nameplate and decorative trim
parts will hold securely after exposure to numerous
chemicals including oil, mild acids and alkalis.
Temperature Resistance The #300LSE “Hi-Strength” adhesive is usable for short
periods (minutes, hours) at room temperatures up to
148ºC, and for intermittent longer periods of time (days,
weeks) up to 93ºC.
Low Service Temperature - 40ºC

Processing Slitting & Die-Cutting:
This adhesive is very aggressive and may be difficult to die cut. Chilling the adhesive to
between 2°C and 10º C will improve the processability. In addition, dies can be
lubricated with Laminoleum evaporative stamping oil
Roll Laminating:
A combination of metal and rubber rollers with moderate pressure is recommended.
Note: Please refer to the 3M Slitting/Die-Cutting Technical Bulletin for further details.

Special Considerations For maximum bond strength the surface should be thoroughly cleaned and dried. Typical
cleaning solvents are heptane or isopropyl alcohol. Consult solvent manufacturer’s
Material Safety Data Sheet for proper handling and storage instructions.
Bond strength can also be improved with firm application pressure and moderate heat,
from 38° C to 54° C, causing the adhesive to develop intimate contact with the bonding
surface.
Ideal tape application range is 21° C to 38° C. Initial tape application to surfaces at
temperatures below 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 generally satisfactory.
