Precision die cuts for permanent automotive exterior hole covering applications with easy quality control



Product description

tesa® 54339 combines a strong PET layer with a powerful acrylic adhesive. 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 secure and precise hole covering application, this product can be delivered with target printing on top of the transparent die cut.

Main features:

  • High transparency for secure application
  • Easy quality control
  • Low VOC according to VDA 278 analysis
  • 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

Main applications

tesa® 54339 is especially suitable for different exterior hole covering applications along the automotive production process.

Example applications are:

  • After e-coat where a good compatibility to UBC (PVC) and sealant is required, e.g. car body platform, wheel houses, 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, our aim is to fully understand your application (including the substrates involved) in order to provide the right product recommendation.
