Application Guidelines

  • Temperature Range:Apply tape at ambient temperatures recommended for the selected adhesive. Solvent-based adhesives allow broader temperature ranges for high-temperature surfaces.
  • Pressure Application:Use uniform pressure along the tape length to ensure full contact with the substrate. Rollers or hand pressure may be applied depending on surface area.
  • Conformability:Smooth tape gradually over curves, corners, and irregular surfaces to prevent bubbles or wrinkles.
  • Liner-Free Handling:Peel and apply the tape carefully to maintain adhesive integrity and prevent misalignment.
  • Mechanical vs. Manual Application:Compatible with both automated systems and manual installation. Ensure consistent tension to avoid stretching or distortion.

Storage and Handling

  • Storage Conditions:Store in a cool, dry environment at +5°C to +25°C with relative humidity below 60%.
  • Roll Orientation:Store rolls horizontally or vertically, protected from dust, direct sunlight, and physical damage.
  • Shelf Life:Typically 12 months from manufacture date under recommended storage conditions.
  • Handling Precautions:Avoid sharp bends, folds, or compressing the tape before application to preserve adhesive properties.

Maintenance Recommendations

  • Periodically inspect bonded areas, especially in high-temperature or high-humidity environments, for peeling or degradation.
  • Reapply tape using the appropriate adhesive type if adhesion is compromised.
  • Ensure workplace safety when handling solvent-based adhesives, including ventilation and personal protective equipment (PPE).
