Key Techniques to Avoid Tape Lifting end
1. Surface Preparation: Ensure the wire surface is clean, dry, and free from oil/grease. Avoid contaminants like talcum powder or silicone residue that reduce adhesion.
2. Proper Application:
- Maintain tension while wrapping; loose overlaps cause lifting.
- Cut tape at 45° angles close to the harness for secure edges.
- Finish with 3 tight end wraps using thumb pressure (not fingertips)
3. Material Selection:
Use PVC/PE tape for thick harness ends to balance thickness
Avoid PVC tape in high-temperature areas (engine bay) where polyester/fabric tapes perform better.
4.Environmental Control:
Store tapes at ≤25°C/60% RH; cold reduces tackiness (winter requires pre-warming)
5.Branch Handling:
Start wrapping from branches toward the main line, maintaining consistent tension.
6.Critical Don’ts:
Never stick tape ends directly onto wires (always wrap fully).
Never use fingertip pressure (oils weaken adhesion).
For high-vibration areas (e.g., engine bays), combine fabric and foam tapes with 70% overlap for 3000-hour durability.
