Product Description
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.
Application Techniques
• 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 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 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
primer 94 for uniform coverage and good adhesion. Allow first application of primer to
dry before applying the second coat. 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: Primer 94 can be removed with isopropyl alcohol. Vigorous scrubbing may
be required.
• Note: Carefully read and follow manufacturer’s precautions and directions for use
when handling cleaning solvents.
