Normal Slitting Tolerance	± 1/32 in. (0.08 mm)
Core Size ID	3.0 in. (76.2 mm)

APPLICATION TECHNIQUES:

Bond strength is dependent upon the amount of adhesive-to-surface contact developed. Firm application pressure helps develop better adhesive contact and improves bond strength.

To obtain optimum adhesion, the bonding surfaces must be clean, dry and well unified. Some typical surface cleaning solvents are isopropyl alcohol or heptane.

Note: Carefully read and follow the manufacturer's precautions and directions for use when working with solvents.

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 because the adhesive becomes too firm to adhere readily. However, once properly applied, low temperature holding is generally satisfactory.

GENERAL INFORMATION:

3M™Adhesive 340 is a medium-firm acrylic that provides a combination of high initial adhesion to a wide variety of materials, including many plastics.
3M™Double Coated Tapes 9824, 9828, 9828HL and 9828PC have a film carrier, which can add dimensional stability to foams and other substrates. The carrier also provides easier handling during slitting and die-cutting.
3M™Double Coated Tape 9456 has a tissue carrier, which adds dimensional stability for handling, while still maintaining the flexibility of a free film adhesive.
Tape 9828HL has a heavy 12 point liner.
Tape 9828PC has a 74# polycoated kraft liner for moisture stability.

APPLICATION IDEAS:
