Product description

tesa® 54349 combines a strong PET layer, consisting of 90% post-consumer recycled (PCR) content, with a powerful solvent-free acrylic adhesive including bio-based tackifiers. This product is optimized for the automotive industry to securely cover holes that require excellent sealing properties in combination with very high-temperature resistance. To ensure a secure and precise hole covering application, this product can be delivered with target printing on top of the transparent die cut.

Product Features

  • 90% post-consumer recycled (PCR) PET content in backing
  • High transparency for secure application and easy quality control
  • Excellent puncture resistance and stone chipping protection
  • Excellent temperature resistance up to 180°C
  • Reliable corrosion protection
  • Good paint anchorage and UBC (PVC) compatibility
  • Very good resistance to chemicals
  • Secure adhesion on steel, aluminum, plastics, painted substrates, and reinforced plastic substrates in automotive lightweight constructions, e.g. CFRP

Application Fields

tesa® 54349 is especially suitable for various exterior hole covering applications along the automotive production process. Example applications are:
  • After e-coat where good compatibility to UBC (PVC) and sealing is required, e.g. car underbody, wheel arches, engine compartment
  • Before paint shop where good paint compatibility is essential
  • At the assembly line for hole covering on all car body areas, e.g. pillars, rocker, front/rear floor
To ensure the highest performance possible, we aim to fully understand your application (including the substrates involved) in order to provide the right product recommendation.
