3M VHB Window Tape G45
3M VHB Window Tape G45
Product Description 3M™ VHB™ Window Tape is a conformable double-coated pressure sensitive
acrylic foam tape with a chemistry that has outstanding durability, UV resistance
and temperature performance. Unlike other foam types, the high strength acrylic
foam is viscoelastic in nature which gives energy absorbing and stress relaxing
properties that provides this tape with its unique characteristics.

Application Techniques For maximum bond strength, all non-glass surfaces should be thoroughly cleaned with a 50:50
mixture of isopropyl alcohol* and water to remove contaminants. Glass surfaces should be
cleaned with a 70/29.5/0.5% mixture of IPA/water/silane solution prior to tape application.*
Pre-mixed solutions are commercially available for a simple cleaning and glass preparation
method. Glass is hydrophilic or “water-loving” in nature, meaning water can undercut a tape,
adhesive or sealant bond over time. A silane coupling agent in the cleaning solution reacts with
the glass to create a hydrophobic or “water-hating” bonding surface. Further surface preparation
and application bonding information is available in the following 3M Technical Bulletins:
“3M™ VHB™ Tape Glass Bonding and Silane Coupling Agents” 70-0702-9983-2
“Surface Preparation for 3M™ VHB™ Tape Applications” 70-0704-8701-5
• Ideal tape application is accomplished when temperature is between 70° and 100°F (21°
and 38°C) and the bond is allowed to dwell 72 hours. Initial tape application to surfaces at
temperatures below 60°F (16°C) is not recommended.
• 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.
*Consult manufacturer’s directions for use and precautions when using cleaning solvents. This cleaning recommendation may
not be compliant with the rules of certain Air Quality Management Districts in California; consult applicable rules before use.
Application Ideas • Excellent adhesion to a broad range of high and medium surface energy substrates common
in the window & door industry including glass, metal, vinyl, composite materials and
many paint formulations.

Product Use 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.
