Features 3M™ Repositionable Tapes 665 and 666 have a medium tack adhesive on both sides of
the tape.
Good adhesive anchorage to the film carrier provides one-piece tape removal from
many surfaces.
Slight side-to-side adhesion differential, therefore specific side removal can be
accomplished if applied properly.
The higher tack side of 3M tape 665 is on the face side (interior of roll).
The higher tack side of 3M tape 666 is on the linered or back side (exterior of roll).
The linerless feature of 3M tape 665 can help simplify manual or automatic dispensing.
No special liner removal equipment is required.
The complete plastic construction of both tapes provides a hot wire cuttable feature for
plastic packaging.
3M™ Repositionable Tapes 9415PC and 9416 have a low tack adhesive on the back side
(exterior of roll) and a high tack (“permanent”) adhesive on the face side (interior of roll).
This means liner covers the low tack adhesive and the high tack adhesive is exposed when
the tape is unwound.
The low tack adhesive side allows for removal from many films, foils, and papers and
will not cause delamination from most paper stock. In many cases this side can be reused
numerous times. The user should perform specific tests to determine the product’s
suitability for the particular application.
Flexible materials will adhere better to the low tack adhesive than will rigid materials
(e.g. paper vs. cardboard). It may also be necessary to remove curl from certain
materials to avoid material separation from the tape over time.
3M™ Repositionable Tape 928 is identical to 3M tape 9416 for the hand-held ATG
applicator.
3M™ Repositionable Tapes 9425 and 9425HT have a medium tack adhesive on the back
side (exterior of roll) and a high tack (“permanent”) adhesive on the face side (interior of
roll) of the tape. This means liner covers the medium tack adhesive and the high tack
adhesive is exposed when the tape is unwound.
The medium-tack adhesive allows removal from many foils and films without adhesive
residue. In many cases, the tape can be reused numerous times. The user should perform
specific tests to determine the product’s suitability for the particular application.
The moisture stable liner improves processing of parts and ease of liner removal.
The polyester film carrier of 3M tape 9425HT provides dimensional stability, improved
handling for die cutting and laminating, as well as providing higher temperature
resistance.
3M™ Repositionable Tape 9449S is a single linered low tack laminating adhesive.
The liner is non-siliconized on the back side (adhesive side) which allows for the
construction of custom labels that are easier to handle, consistently maintaining
registration on-press when printing and converting.
The low tack allows easy removal of labels from substrates with little or no adhesive
residue.

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. Some typical surface cleaning solvents are isopropyl alcohol or heptane.*
*Note: Carefully read and 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. An exception is 3M™
Repositionable Tapes 9425 and 9425HT which can be applied at temperatures as
low as 32°F (0°C).
Storage Store in original cartons at 70°F (21°C) and 50% relative humidity.
Shelf Life If stored under proper conditions, these products retain their performance and
properties for two years from date of manufacture.
