How to Use
To apply 3M™ Extreme Sealing Tape 4411B:
- Surface Preparation: Ensure the surface is clean, dry, and free from contaminants. Use a 50:50 mixture of isopropyl alcohol and water for cleaning.
- Application: Apply the tape over the area to be sealed, keeping the release liner in place to prevent overstretching.
- Adhesion: Remove the release liner and press the tape firmly onto the surface using a roller or hand pressure to ensure good contact.
- Overlap Joints: For overlapping joints, ensure at least a 2 cm (3/4 in) overlap and apply firm pressure to secure the seal.
The tape provides an immediate seal, with full bond strength achieved after 24 hours
Cautions
- Apply at temperatures between 50°F (10°C) and 100°F (38°C) for optimal adhesion.
- Avoid stretching the tape during application to maintain seal integrity.
- Store in a cool, dry place away from direct sunlight.
- Ensure proper surface preparation to achieve the best results.
