Installation Guide
Step 1: Surface Cleaning
- Clean the bonding surface to remove dust, oil, grease, and contaminants.
- Ensure the surface is dry before applying primer.
Step 2: Apply Tape Primer 94
- Apply a thin, uniform coating of 3M Tape Primer 94 to the bonding area.
- Avoid excessive primer application.
Step 3: Allow Primer Drying
- Allow the primer to dry completely before applying adhesive tape.
- Drying time depends on temperature, humidity, and substrate conditions.
Step 4: Apply Adhesive Tape
- Apply 3M VHB™ tape or compatible adhesive product.
- Press firmly to ensure good contact between tape and substrate.
Step 5: Complete Bonding
- Allow sufficient dwell time for maximum adhesive strength development.
- Avoid heavy loading immediately after application.
Storage
- Store in the original sealed container.
- Keep in a cool, dry, and well-ventilated area.
- Avoid direct sunlight and heat sources.
- Keep container tightly closed when not in use.
- Follow recommended shelf-life requirements.
FAQ
Q1: What is 3M Tape Primer 94 used for?
3M Tape Primer 94 is used to improve the adhesion of pressure-sensitive adhesive tapes on difficult-to-bond surfaces.
Q2: Can Primer 94 be used with 3M VHB™ tape?
Yes. It is commonly used to enhance bonding performance of 3M VHB™ tapes and other adhesive products.
Q3: Which materials require Primer 94?
