Adhesive Transfer Tapes with Adhesive 350

9442 • 9445 • 9482PC • 9485PC • 9485EK • 9675

Product Description These 3M™ Adhesive Transfer Tapes with 3M™ Adhesive 350 are a modified acrylic adhesive ideal for very high-bond strength to many surfaces. They have excellent chemical resistance and bold strength even at elevated temperatures. These tapes are offered with a fiber reinforced adhesive which is important for roll stability in narrow widths. Tapes using adhesive 350 are designed for temperature exposure to 450°F (232°C) for short periods of time and up to 300°F (149°C) over long time frames.

This adhesive is a good choice for applications which require adhesion to Low Surface Energy plastics, powder coatings and oily metals.

Construction

Technical Data September, 2002

Adhesive Product Thickness Number (mils) Liner material - thickness

9442 2.0 (.05 mm) 55# Densified Kraft - 3.2 mils thick

9445 5.0 (.127 mm) 55# Densified Kraft - 3.2 mils thick

9482PC 2.0 (.05 mm) 62# Polycoated Kraft - 4.2 mils thick

9485PC 5.0 (.127 mm) 62# Polycoated Kraft - 4.2 mils thick

9485EK 5.0 (.127 mm) 78# Extensible Polycoated Kraft - 5.7 mils thick

9675 5.0 (.127 mm) 83# Polycoated Kraft lay flat - 6.2 mils thick

Note: These thicknesses are nominal values calculated from the adhesive areal density, the actual control value, used in manufacturing. Please note that temperature performance reflects liner off, completed bonds. The poly coated kraft liners melt at lower temperatures and silicone contamination may occur if exposed to high temperature with the liner attached.

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 350 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 water 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 decorate 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 Adhesive 350 is usable for short periods (minutes, hours) at temperatures up to 350°F (177°C) and for intermittent longer periods (days, weeks) up to 250°F (121°C).

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

Shelf Life: Product retains its performance and properties for two year from date of manufacture if properly stored at room temperature conditions of 72°F (22°C) and 50% R.H. Storage in a plastic bag is recommended.

Available Sizes Core Size: The above tapes are offered on a 3.0 inch (76.2 mm) paper core.

General Information • Excellent bond to metal and high surface energy plastics.

• Outstanding temperature and chemical resistance.

• Two adhesive thicknesses: 2 mil for thin profile labels and 5 mil for rougher surfaces.

• Available on various liners for specialized processing:

- 55# Densified Kraft for rotary die-cutting

- 62# Polycoated Kraft for steel rule die-cutting

- 83# Polycoated Kraft for lay flat applications

- 78# Extensible Kraft for conformable applications

Application Techniques

For maximum bond strength the surface should be thoroughly cleaned and dried.

Typical cleaning solvents are heptane or isopropyl alcohol. Consult 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 (for metal surfaces only), from 100°F (38°C) to 130°F (54°C), causing the adhesive to develop intimate contact with the bonding surfaces.

Application Ideas Ideal adhesive application temperature range is 70°F to 100°F (21°C to 38°C). Initial 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 our toll free 3M sales assistance number at 1-800-362-3550.

2 mil thick tapes may generally be used for joining materials that are relatively smooth, thin and have low residual stress. For materials with a rough or textured surface, the thicker adhesive film of the 5 mil tapes would be more appropriate for evaluation.
