3M™Repositionable Tapes 665 • 666 • 9415PC • 9416 • 9425 • 9425HT • 9449S

3M™ Repositionable Tapes are double coated tapes that are ideal for applications where one or both parts need to be repositioned or removed easily.

• 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 side adhesive side allows for removal without adhesive residue 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.

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).

• Reclosable bags or envelopes.
• Core starting and end tabbing of papers, foils, and films.
• Removable stickers and labels.
• Point of purchase displays.

All statements, technical information and recommendations contained in this document are based upon tests or experience that 3M believes are reliable. However, many factors beyond 3M's control can affect the use and performance of a 3M product in a particular application, including the conditions under which the product is used and the time and environmental conditions in which the product is expected to perform. Since these factors are uniquely within the user's knowledge and control, it is essential that the user evaluate the 3M product to determine whether it is fit for a particular purpose and suitable for the user's method of application.
