3M Safety-Walk Primer 94

Adhesion Promoter for 3M™ VHB™ Tapes

3M Safety-Walk Primer 94 is a highly effective adhesion promoter formulated to improve the bond strength of 3M™ Safety-Walk Tapes or 3M™ VHB™ Tapes to a variety of difficult-to-bond surfaces. This fast-drying primer enhances tape adhesion to materials such as polyethylene, polypropylene, ABS, PET/PBT blends, concrete, wood, glass, metal, and painted surfaces.

Ideal for industrial and commercial bonding applications where surface energy or texture may compromise performance, Primer 94 is a trusted choice to ensure long-lasting, high-strength bonds.

🌟 Key Features

• ✅ Improves Adhesion – Increases bonding effectiveness on low surface energy (LSE) and textured substrates

• 🧪 Versatile Use – Compatible with plastics, metals, painted surfaces, and more

• ⏱ Fast Drying – Ready for tape application in approximately 5 minutes at room temperature

• 🛠 Flexible Application – Can be applied with brush, swab, roller, or spray

🧼 Surface Preparation

• Ensure surfaces is clean and dry

• Clean using a 50/50 mix of isopropyl alcohol and water with a lint-free cloth

🖌 Application Guidelines

• Shake well before use

• Apply a thin, even coat using minimum amount to fully cover the bonding area

• Dry time: ~5 minutes at room temperature

• Porous surfaces may require two coats (allow the first to dry fully before applying the second)

• Application methods: brush, swab, pressurized flow gun, or knurled roller

Note: Keep surfaces clean and uncontaminated after priming and before tape application for best results.
