How to use this tape?

Clean

: For maximum bond strength,the surface must be clean, dry, smooth, have no rust and oil pollution. Typical cleaning solvents are heptane or isopropyl alcohol.

Pressure

: Pressure on the adhesive and the surface can help improve bond strength,roller or platen can be used.

Time

: After application, the bond strength will increase asthe adhesive flows onto the surface.At room temperature approximately 50 after 24 hoursand 100% after 72 hours.

Temperature

: Ideal application temperature range is 70F to 100F (21degree centigrade to 38degree centigrade).Operating temperature should not be below 10 degree centigrade, the temperature is too low, will lead to cure time longer. If temperature is too low, move material and adhesive tape into the warm indoor storage or heating treatment.

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 - 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
