This 3M Primer 94 Pen can be used to promote adhesion of 3M tapes to surfaces such as polyethylene, polypropylene, ABS, PET/PBT blends, concrete, wood, glass, metal, and painted metal surfaces.
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.
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 the 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 the first application of primer to dry before applying the second coat.
3M primer 94 may be applied with a brush or swab. It can also be applied with a pressurized flow gun, knurled roller or other similar types of application equipment.
