Setup and Preparation
Proper surface preparation is crucial for optimal adhesion and performance of the AC36 DUCTape.
- Surface Cleaning: Ensure the surface where the tape will be applied is clean, dry, and free of any dust, dirt, oil, grease, or other contaminants. Use an appropriate cleaner if necessary and allow the surface to dry completely.
- Temperature Conditions: For best results, apply the tape in temperatures above 40°F (4°C). Extreme cold can reduce initial tack.
- Unrolling: Carefully unroll the desired length of tape from the roll. Avoid touching the adhesive side excessively to maintain its stickiness.

Operating Instructions and Applications
The AC36 DUCTape is versatile and can be used for various applications:
- HVAC Systems: Ideal for sealing and joining ductwork, ensuring airtight connections in heating, ventilation, and air conditioning systems.
- Abatement Projects: Suitable for sealing off areas during asbestos, lead, or fiberglass abatement procedures due to its strong adhesion and durability.
- Weatherproofing: Can be used to seal gaps and cracks to prevent water and air infiltration, providing temporary weather protection.
- Flex-Duct Connections: Acts as an effective gasket material for connecting flexible ducts, providing a secure and durable seal.
- General Maintenance: Useful for temporary repairs, bundling, patching, and other general-purpose maintenance tasks around the home or job site.
Application Technique:
Apply the tape firmly and smoothly to the desired surface. Press down along the entire length of the tape to ensure maximum contact and to eliminate any trapped air bubbles. For critical applications, consider overlapping tape sections for enhanced strength and sealing.

Maintenance and Care
To ensure the longevity and effectiveness of your IPG AC36 DUCTape:
- Storage: Store unused rolls in a cool, dry place, away from direct sunlight and extreme temperatures. High heat can degrade the adhesive over time.
- Protection: Keep the tape roll sealed in its original packaging or a protective bag when not in use to prevent dust, dirt, and debris from accumulating on the edges and adhesive surface.
- Handling: Avoid dropping the roll, which can damage the edges and make unrolling difficult.
Troubleshooting
Common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Poor Adhesion | Dirty, wet, or oily surface; low application temperature; insufficient pressure during application. | Ensure surface is clean, dry, and free of contaminants. Apply tape in recommended temperature range. Apply firm, even pressure across the tape. |
| Tape Tearing Unevenly | Dull cutting tool; improper tearing technique. | Use a sharp utility knife or scissors for clean cuts. For manual tearing, ensure a quick, decisive tear. |
| Adhesive Residue After Removal | Tape left on surface for extended periods; surface type. | For temporary applications, remove tape promptly. Use a commercial adhesive remover suitable for the surface material. |
