Description:
Provide the convenience and simplicity of a tape fastener
Ideal for use in many interior and exterior bonding applications
Can replace rivets, spot welds, liquid ashesives and other permanent fasterners.
Acrylic foam is viscoelastic in nature, which gives the foam energy absorbing and stress relaxing properties.
The acrylic chemistry provides outstanding durability performance.
• Application
High adhesive,excellent performance for vibration and anti-crack,good weather resistance.anti-chemicals etc..
Good isolation and buffering,applied for furniture,construction and flexible conjunction for decoration.
Automobile foam tape used for rough and even surface.sticking signboard,mirror,map etc.
Apply to elimanating sound and reduce vibration packing for eletric accessories and protection for glass board,etc..

Q. What percent of the final bond strength can I expect immediately after application? After 24 hours? After 72 hours?
A. Immediately after an application is made, about 60% of the bond strength is achieved. As the adhesive continues to wet-out the surface, you can expect the bond to be at about 75% - 80% after 24 hours. After 72 hours, 95%+ of the bond strength is achieved. The bond will continue to build with time.
Q. Is the tape solvent resistant?
A. Yes, 3M acrylic foam tapes are resistant to most common automotive solvents like gasoline, diesel fuel, washer solvent, etc. Solvent resistance is a function of type of solvent, time of exposure and temperature.
Q. Why doesn`t the tape feel sticky?
A. 3M`s high performance acrylic adhesives tend to be firm and dry to the touch. They are designed to bond materials other than skin. The adhesives used are designed to give optimum performance and adhesion to automotive substrates and components. The natural oils and moisture of skin can vary from person to person and affect the "thumb appeal" of the 3M Acrylic Foam Tape. To one person the tape can feel very sticky and to another it can feel much less sticky to the touch. The difference in "thumb appeal" is in the variation of the 2 individual`s skin surfaces not the adhesive.
Q. The part is not adhering to the vehicle. What might be wrong?
A. Areas to investigate for poor adhesion or performance include:
Check for surface contamination. The substrates must be clean and free of any contaminant. This is the most common cause of poor adhesion.
Check for surface match. Are the two surfaces to be bonded a good match?
Check for proper application pressure and wet-out.
Check the back of the component for flatness.
Check the installation process for proper procedures.
