9495LE •9474LE •9490LE
Product Description3M™Double Coated Tapes 9495LE, 9474LE and 9490LE with 3M™Adhesive
300LSE provides high bond strength to most surfaces, including many low surface
energy plastics such as polypropylene and powder coated paints. The acrylic adhesive
also provides excellent adhesion to surfaces contaminated lightly with oil typically ud
with machine parts. 3M tape 9490LE offers the added feature of 3M™Adhesive
300MP on one side to provide excellent bond strength to a variety of foam and fabric
materials.

Note 1:Faceside (FS) adhesive is on the interior of the roll, expod when unwound.
Note 2:Backside (BS) adhesive is on the exterior of the roll, expod when liner is removed.
Note 3:PET (Polyester).
Note 4:The caliper listed is bad on a calculation from manufacturing controlled adhesive coat
weights using a density of 1.012 g/cc. While past data pages have listed a nominal
caliper of 6.0 mils for the tapes, the coat weight has not changed.
Note 5:Backside liner is primary (stays with die cut part); Faceside is condary (removed first).

Application Techniques Bond strength is dependent upon the amount of adhesive-to-surface contact developed. Firm application pressure and moderate heat, from 100°F (38°C) to 130°F (54°C), will assist the adhesive in developing initmate contact with the bonding surface.
灰色关联度分析
To obtain optimum adhesion, the bonding surfaces must be clean, dry and well unified. Some typical surface cleaning solvents are isopropyl alcohol or heptane.*
Ideal tape application temperature range is 70°F to 100°F (21°C to 38°C). Initial tape application to surfaces at temperatures below 50°F (10°C) is not recommended becau the adhesive becomes too firm to adhere readily. However, once properly applied, low temperature holding is generally satisfactory.
*Note:Carefully read and follow the manufacturer’s precautions and directions for u when working with solvents. The cleaning recommendations may not be
compliant with the rules of certain Air Quality Management Districts in
California; consult applicable rules before u.
Features•The tapes have a moisture resistant polycoated kraft liner which can withstand high
humidity conditions with minimal cockling or wrinkling.
•The tapes have a film carrier which can add dimensional stability to foams and other
substrates and also makes it easier to handle the tape during slitting and die-cutting.
•3M™Double Coated Tape 9474LE features a dual liner for ea in lective die cutting.
•The bond strength of 3M™Adhesive 300LSE increas as a function of time and
temperature, and has very high initial adhesion.
Environmental Performance Humidity Resistance: High humidity has minimal effect on adhesive performance.
No significant reduction in bond strength is obrved after exposure for 7 days at 90°F (32°C) and 90% relative humidity.
UV Resistance: When properly applied, nameplates and decorative trim parts are not adverly 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 158°F (70°C)
4 hours at -20°F (-29°C)
4 hours at 73°F (22°C)
Chemical Resistance: When properly applied, nameplate and decorative trim parts will hold curely after exposure to numerous chemicals including oil, mild acids and alkalis. General purpo steel rule die-cutting58# PCK

1.Rotary processing, tape only, on a densified (outside of #4994) kraft liner. In this process, the tape
waste will stay with the 58# PCK liner, leaving adhesive die-cuts dispensable from the #4994 (densified kraft) liner.
2.Rotary processing for finished parts. If a densified kraft (DK) liner is necessary,the adhesive should be first laminated to the substrate with pressure. After lamination, remove the 58# PCK liner and laminate the outside of the #4994(DK) liner.Adding Liners for 3M ™Double Coated Tapes with Adhesive 300LSE
Application Equipment
To apply adhesives in a wide web format, lamination equipment is required to ensure acceptable quality. To learn more about working with pressure-nsitive adhesives plea refer to technical bulletin, Lamination Techniques for Converters of Laminating Adhesives (70-0704-1430-8).
