MOUNTING GUIDELINES, ST-675-SIAD-001 TAG
For the antenna, some container models may not have adequate space between the edge of the
door and the locking bar. In these instances, the antenna may be mounted on the far side of the
locking bar.
3.2 Surface Preparation
The tag shall be fastened to the container utilizing 3M 5952 family VHB tape; as such surface
preparation is key to the success of the bond. Further information can be found at 3M’s
website.
3.2.1 Summary
Most substrates are best prepared by cleaning with a 50:50 mixture of isopropyl alcohol (IPA) and
water* prior to applying 3M™ VHB™ Tapes. Exceptions to this general procedure that may require
additional surface preparation include:
• Heavy Oils: A degreaser or solvent-based cleaner may be required to remove heavy oil or
grease from a surface and should be followed by cleaning with IPA/water.
• Abrasion: Abrading a surface, followed by cleaning with IPA/water, can remove heavy dirt or
oxidation and can increase surface area to improve adhesion.
• Adhesion Promoters: Priming a surface can significantly improve initial and ultimate
adhesion to many materials such as plastics and paints.
• Porous Surfaces: Most porous and fibered materials such as wood, particleboard, concrete
etc. need to be sealed to provide a unified surface.
• Unique Materials: Special surface preparation may be needed for glass and glass-like
materials, copper and copper containing metals and plastics or rubber that contain components
that migrate (e.g. plasticizers).
3.2.2 General Procedure
• To obtain optimum adhesion, the bonding surfaces must be well unified, clean and dry. Typical
surface cleaning solvents are IPA/water mixture (rubbing alcohol) or heptane.*
• Bond strength is dependent upon the amount of adhesive-to-surface contact developed. Firm
application pressure develops better adhesive contact and helps improve bond strength.
Generally, this means that the tape should experience at least 15 psi (100 kPa) in roll down or platen
pressure.
• After application, the bond strength will increase as the adhesive flows onto the surface. At room
temperature, approximately 50% of the ultimate strength will be achieved after 20 minutes, 90% after
24 hours and 100% after 72 hours. In some cases, bond strength can be increased and ultimate bond
strength can be achieved more quickly by exposure of the bond to elevated temperatures (e.g. 150°F
[66°C] for 1 hour).
