Best Practices for 3M 86A
The bonding surface must be smooth, clean, dry and free of foreign matter. If necessary, the surface should be sanded to the smoothness attainable with 320 grit sandpaper. Clean the surface with isopropyl alcohol and allow the surface to dry prior to the application of 3M™ Adhesion Promoter 86A.
Note: Towels or cloths used in the cleaning process should be untreated and lint free.
Note: When using solvents, extinguish all ignition sources, including pilot lights. Read and follow manufacturer's warnings and directions for use.
Wipe the surface with the pre-saturated 3M 86A Promoter wipe or with cheesecloth wetted with 3M 86A Promoter, using the minimum amount that will coat desired surface. More is not better. Allow to dry for 10 minutes. For best results, apply 3M Polyurethane Protective Tape with acrylic adhesive within two hours to the promoted surface.
