When is it necessary to use 3M™ Primer 94?
3M™ Primer 94 is recommended when a standard double-sided tape may not achieve maximum adhesion due to the material's characteristics.
It is particularly useful on a wide range of substrates such as:
- Polyethylene (PE)
- Polypropylene (PP)
- ABS
- PET/PBT
- Painted surfaces
- Metals
- Glass
- Wood
- Concrete
Application of Primer 94 increases initial adhesion and improves the reliability of the bond over time, especially when using 3M™ VHB™ tapes, adhesive films, and vinyl graphics.
Technical Features and Benefits
Improves adhesion on difficult materials
Promotes the adhesion of 3M tapes to:
- PE
- PP
- ABS
- PET/PBT
- Rubber
- Metals
- Wood
- Concrete
Increases bond reliability
Improves:
- Initial adhesion
- Final adhesion
- Bonding life
Quick drying
Typically dries in about 5 minutes at room temperature, allowing the tape to be applied quickly. It is important to apply a thin, even layer; two coats may be necessary on porous surfaces.
Compatible with numerous 3M adhesive systems
Perfect for:
- 3M VHB
- Double-sided tapes
- Adhesive films
- Vinyl graphics
Frequently Asked Questions (FAQ)
Q: How do I properly apply Primer 94?
A: Thoroughly clean the surface (3M recommends 3M™ VHB Surface Cleaner or a 50:50 mixture of isopropyl alcohol and water for contaminated surfaces), apply a thin, even coat of Primer 94 with a brush, pad, or other suitable applicator, wait until completely dry, and then apply the tape. Avoid over-applying the primer, as too thick a coat can reduce performance.
Q: Is Primer 94 compatible with 3M™ VHB™ Tapes?
A: Yes. It was developed specifically to improve the adhesion of 3M™ VHB™ Tapes and other 3M adhesive systems to a variety of challenging substrates.
Q: How long does it take for it to dry?
A: Approximately 5 minutes under normal ambient conditions before applying the tape.
