3M™ Tape Primer 94 is a specialized adhesion promoter designed to enhance the bonding strength of tapes, films, and vinyl graphics on challenging surfaces such as polyethylene, polypropylene, ABS, PET/PBT blends, concrete, wood, glass, metal, and painted metal. It is widely used in industries like automotive detailing, construction, signage, electronics, metalworking, transportation, and general industrial applications. This primer is particularly effective for improving adhesion of 3M™ VHB™ Tape on various plastic, rubber, painted, and bare metal substrates.

Key Features and Highlights

• Adhesion Promotion: Enhances bonding on difficult-to-stick-to surfaces like polyethylene, polypropylene, ABS, and PET/PBT blends.
• Versatile Application: Commonly used for automotive detailing to improve adhesion of film and vinyl graphics.
• Application Methods: Can be applied with a brush, swab, pressurized flow gun, or knurled roller for small or large areas.
• Clear Finish: Dries to a transparent finish, maintaining the aesthetic of the applied surface.
• Quick Drying: Dries in approximately 5 minutes at room temperature (60°F–80°F or 15°C–27°C), enabling efficient use.
• Clean-Up: Easily cleaned with isopropyl alcohol or acetone, though vigorous scrubbing may be required.
• Solvent-Based Composition: Liquid form with a yellow hue, designed for industrial and occupational use only (not for consumer sale).

Application Tips

1. Surface Preparation: Ensure the surface is clean and dry before applying a thin, uniform coat of primer.
2. Minimal Application: Use the minimum amount necessary to avoid sub-optimal results from over-application.
3. Drying Time: Allow the primer to dry completely (typically 5 minutes) before applying tape.
4. Porous Surfaces: May require two coats for uniform coverage and optimal adhesion. Let the first coat dry before applying a second.
5. Storage: Store at 60°F–80°F (15°C–27°C) to maintain product integrity.
6. Clean-Up: Use isopropyl alcohol or acetone for removal, with vigorous scrubbing if needed.
