Product Description 3M™ Adhesion Promoter 86A is a liquid “primer” designed to be used with 3M™ Polyurethane Protective Tapes and Boots and other acrylic adhesives to enhance initial adhesion in demanding situations. 3M 86A promoter is designed to promote faster initial adhesion to certain types of surfaces, such as polyurethane paint, epoxy primers, or epoxy composites. It is not intended for use where the acrylic adhesive would be in direct contact with aluminum, stainless steel, carbon, steel, or glass. Typical Performance Characteristics 3M 86A Promoter allows for faster initial adhesion build rate of 3M™ Polyurethane Protective Tapes and Boots with acrylic adhesives to certain surfaces.

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 (i.e. - cheesecloth or Kimwipe ®). 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. * - 2 -
If gelling occurs, place the can of 3M™ Adhesion Promoter 86A into a zip-lock plastic bag to keep can and label dry. Place the can of 3M 86A Promoter into a container of hot tap water (120-140°F [49-60°C] max.) for 30 minutes. The gels will go back into solution with no performance effects on the product. W ARNING: This is a flammable liquid! Do not heat in boiling water or on top of stove/hot plate, in oven or open flames.
