3M™ Tape Primer 94 can be used to promote adhesion of 3M tapes to surfaces such

polyethylene, polypropylene, ABS, PET/PBT blends, concrete, wood, glass, metal

and painted metal surfaces.

Surface Preparation: The bonding surface must be relatively clean and dry.

Contaminated surfaces should be cleaned with a 50/50 Isopropyl Alcohol and

water mixture. A clean lint-free cloth should be used.

Application: Shake 3M primer 94 well before using. Apply a thin uniform coating

to the bonding surface using the minimum amount that will fully coat the surface.

Allow 3M primer 94 to dry thoroughly before applying tape. This is usually

accomplished in 5 minutes at room temperature. Be sure the primed surface

remains free from contaminants prior to applying the tape. Porous surfaces may

require 2 applications of 3M primer 94 for uniform coverage and good adhesion.

Allow first application of primer to dry before applying the second coat. 3M primer

94 may be applied with brush or swab. It can also be applied with a pressurized

flow gun, knurled roller or other similar type of application equipment.

Clean up: 3M primer 94 can be removed with isopropyl alcohol or 3M Citrus Base Cleaner. Vigorous

scrubbing may be required.
