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:

Application:

• 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.
