Application Techniques
• Bond strength is dependent upon the amount of adhesive-to-surface contact
developed. Firm application pressure helps develop better adhesive contact and
improve bond strength.
• To obtain optimum adhesion, the bonding surfaces must be clean, dry and well
unified. Typical surface cleaning solvents are isopropyl alcohol and water (rubbing
alcohol) or heptane.
Note:
Be sure to follow the manufacturer’s precautions and
directions for use when using 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
• Tape 928 is a low-tack adhesive which allows removal from many papers, foils, and
films without adhesive residue and will not cause delamination of most paper stocks. In
many cases, the tape can be reused numerous times.
• Tape 928 will not bleed into most paper stocks which helps minimize possible
discoloration or staining.
• Flexible materials will adhere better to tape 928 than will rigid materials (e.g., paper vs.
cardboard). It may also be necessary to remove curl from certain materials to avoid
having them pull away from the low-tack adhesive of tape 928 over a period of time.
• The extended liner (XL) on tape 970XL provides a dry edge on each side of the roll for
adhesive protection. Liner extension is 1/16 in. (1.6 mm) on each side which decreases
coating 1/8 in. (3.2 mm) overall.
• ATG tapes are a reverse wound version of standard 3M Adhesive Transfer
and Double Coated tapes for use in the Scotch
®
ATG hand-held dispensers.
