tesa® 54332 FireGuard

Sealing Patch for hole covering applications

Product description

tesa® 54332 FireGuard combines a fire- and heat-resistant aluminum laminated glass cloth layer with a thick acrylic adhesive sealer.

Application Fields

tesa® 54332 FireGuard can be applied before and after paint shop along the automotive production process, e.g. floor areas directly above the battery housing.
Main product features:
  • Fire proofness of car body holes > 5 minutes at 500 °C (open flame)
  • Reliable corrosion protection and sealing against water ingress
  • Good puncture resistance
  • Temperature resistance (dimensional stability) up to 200 °C
  • Good UBC (PVC) compatibility and paint anchorage
  • Secure adhesion to steel, aluminum, plastics, painted substrates, and reinforced plastic substrates in automotive lightweight constructions
In case the product will be applied in the underbody area we are recommending an additional coverage due to low stone chipping performance.
Our aim is to fully understand your application (including the substrates involved) in order to provide the right product recommendation and to ensure the highest performance possible.
