3M Primer 94 - Vehicle Wrap & Tape Adhesion Promoter
3M™ Tape Primer 94 - 236ml
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.
This water-based formulation removes oils, grease, and mold release agents quickly and easily. The best way to improve adhesion on galvanized steel, plastics, and other surfaces. Heavily soiled surfaces may require a second application. Be sure to read and follow precautions and directions—see Technical Data below for more information on application procedures.
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 acetone. Vigorous scrubbing may be required. Test in small area to insure acetone will not affect the substrate surface
