3M Tape Primer 94 promotes adhesion of tape and adhesives. 1 Gallon.
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.
