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.

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.

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

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.
