tesa® 54336 Interior Performance Sealer

The Interior High Performance Sealer for permanent hole covering applications

Product description

tesa® 54336 Interior High Performance Sealer is a strong PET with an extra thick adhesive layer. The product is optimised for the automotive industry to cover unused interior holes that require excellent sealing properties in combination with good temperature resistance.


  • Reliable corrosion protection as e.g. punch burrs will be securely sealed by 400µm adhesive layer
  • Excellent temperature resistance up to 190°C
  • Good paint and UBC (PVC) compatibility
  • Secure adhesion on painted substrates and on reinforced plastic substrates in automotive lightweight constructions, e.g. CFRP

Main applications

tesa® 54336 is especially designed for interior hole covering applications at the assembly line or paint shop area to protect exposed punch burrs against corrosion. Its high temperature resistance provides freedom to decide when and where the holes are covered during the manufacturing process:

  • 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 interior Hole Covering on all car body areas, e.g. pillars, rocker, front/rear floor
