Preparing the
Surfae
The first step in making a successful seal is to prepare the surface for bonding. At a
minimum, this means making sure the bonding surface is clean of all contaminants. For
most surfaces, cleaning with a 50:50 mixture of isopropyl alcohol* (IPA) and water works
well. If the substrate is contaminated with heavy oils or grease, a degreaser or strong
solvent may be used to remove the oil, but a final wipe of IPA/water should be used.
For many substrates, a simple cleaning will allow 3M™ Extreme Sealing Tape to bond.
However, adhesion promoters can be used to increase both initial and final bond strength.
The following three primers are commonly used with 3M™ Extreme Sealing Tapes:
Metals and Paints
3M™ Adhesion Promoter 111 (AP111) increases adhesion on most metals and many hard
coatings and paints.
Plastics and Rubbers
3M™ Primer 94 increases adhesion on many plastics and rubbers.
Glass
3M™ Adhesion Promoter 115 (AP115) increases adhesion on glass.
See technical data sheets for adhesion promoter and primer application instructions.
*Consult manufacturer’s directions for use and precautions when using cleaning solvents.
This cleaning recommendation may not be compliant with the rules of certain Air Quality
Management Districts in California; consult applicable rules before use.

Notes:
1. For metals and paints, 3M™ Adhesion Promoter 111 was used to increase adhesion to maximum levels.
2. For glass, 3M™ Silane Glass Treatment AP115 was used to increase adhesion to maximum levels and
to provide long term durability on glass.
3. For plastics, 3M™ Primer 94 was used to increase adhesion to maximum levels. Note that Primer 94
has high levels of VOC’s and may not be available for purchase in all areas.
