TAT-N-AC is a thermally conductive electrically insulating acrylate PSA transfer tape. Through the thermally conductive adhesive the thermal contact is highly improved even at low pressures. Convex and concave surface structures and stack up tolerances are effectively compensated. Materials with different expansion coefficients can easily be bonded. Thus the total thermal resistance is minimised. The tape works well for realizing an effective and cost efficient thermal coupling in a broad field of applications. Above all it is used in applications having little space only and where the permitted weight is limited. Using screws, springs, clips as mechanic fasteners thus becomes superfluous. Its wide thickness range allows the use as gap filler.




PROPERTIES

  • Low thermal resistance
  • Thermal conductivity: 1.0 W/mK
  • Use as gap filler due to wide thickness range
  • Reliable strong adherence on uneven or hardly machineable surfaces
  • Silicone-free
  • Neither mixing of components nor curing processes
  • Replacement of fasteners e.g. screws, clips, etc.
