Adhesive Transfer Tapes with Adhesive 300
927 • 950 • 950EK
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:
Be sure to follow solvent manufacturer’s precautions and directions for use
when using solvents.
• Ideal tape application temperature range is 70°F to 100°F (21° 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 satisfactory.
General Information
• The resistance of these tapes to ultra violet (U.V.) light is fair. Applications where
the adhesive mass is directly exposed to sunlight or other sources of U.V. light
through glass, clear plastic, etc. should be avoided. Edge exposure is generally
satisfactory.
• 3M™ Adhesive 300 has relatively good resistance to moderate amounts of
plasticizers. Applications may be subjectively evaluated by the user testing the tape
in contact with the materials at conditions of 150°F (66°C) for a period of 5-7 days.
• Adhesive 300 will not bleed into most paper stocks which helps minimize possible
discoloration of posters, business forms.
• 3M™ tapes 927 and 950 meet the requirements of U.S. Government Specification
MIL-P-19834B, Amend 1.
Application Ideas
3M™ tapes 927, 950 and 950EK are ideal for attaching a wide variety of similar and
dissimilar materials where an aggressive adhesive with high initial adhesion is desired.
Some applications ideas are:
• Splicing of film, foils, fabrics.
• Laminating adhesive for foams, photos, fabrics, metal or plastic nameplates.
• General purpose holding and mounting applications.
Application Equipment
To apply adhesives in a wide web format, lamination equipment is required to
ensure acceptable quality. To learn more about working with pressure-sensitive
adhesives please refer to technical bulletin, Lamination Techniques for Converters
of Laminating Adhesives (70-0704-1430-8).
