Technical Data

Adhesion Promoter 86A

Application Use:

Note: When using solvents, extinguish all ignition sources, including pilot lights. Read

and follow manufacturer's warnings and directions for use.

1) Surface Preparation

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.* Application of 3M Promoter 86A on bare metal surfaces does not

appreciably enhance adhesive values. The danger in using 3M Promoter 86A on metal

surfaces is that it may transfer to the tape adhesive, if the tape is lifted for repositioning. If

this transfer occurs, the adhesive of the protective tape will be compromised.

Note: Towels or cloths used in the cleaning process should be untreated and lint free

2) Apply 3M 86A Promoter

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.

Note: In many applications only the outer most edges of the application area may require

use of 3M 86A Promoter.

Note: 3M Tape and Boot applications over 3M 86A Promoter will be more difficult to

remove.

Note: If desired, 3M 86A Promoter may be sprayed on the surface, using most conventional

spray equipment. If dilution is required, it may be done with isopropyl alcohol.*
