tesa® 54718 Paintable Noise Blocker

Optimum acoustic insulation die cut for permanent automotive hole covering applications with excellent paintability



Product description

tesa® 54718 Paintable Noise Blocker combines a mineral filled polyolefin layer with a premium cloth top layer and a powerful acrylic adhesive. This product is optimized for the automotive industry to securely cover holes that require excellent acoustic insulation in combination with very good sealing properties.


Main features
  • Excellent acoustic insulation due to high area density of 1.8 kg/m²
  • Very good paint anchorage and UBC (PVC) compatibility
  • High temperature resistance up to 160°C
  • Good sealing properties
  • Good resistance to chemicals on cloth side
  • Secure adhesion to steel, aluminum, plastics, painted substrates, and reinforced plastic substrates in automotive lightweight constructions, e.g. CFRP

Main applications

tesa® 54718 is suitable for different 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. 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.
