Is there any solvent that can be used to aid the removal of TCDT2? It has stuck on a copper piece and won't come off!

Response from Buki at Thorlabs to sebastien.avila: Thank you for participating in our feedback forum. As the 5810 is silver filled, it should have a correspondingly high thermal conductivity. However, this value has not been tested by the manufacturer. Due to the wide range of applications, temperatures, substrates, and environments in which this product can be used, we recommend first testing its fitness for use in your specific application. We would be happy to provide you with a sample for testing. We have contacted you to provide further assistance.

Thermally Conductive Double-Sided Tape

  • Thermally Conductive Double-Sided Acrylic Adhesive Tape
  • 0.009" (0.229 mm) Thick
  • Two Options:
    • TCDT1: 1" Wide x 48" Long (25.4 mm x 1219 mm)
    • TCDT2: 2" Wide x 24" Long (50.8 mm 610 mm)
  • Great Alternative to Heat-Cured Adhesives, Screw Mounting, or Clip Mounting
  • Provides a High Bond Strength to a Variety of Surfaces
  • Can be Removed without Damaging Parts

The thermally conductive, double-sided tape consists of a superior bond strength, pressure-sensitive acrylic adhesive loaded with titanium diboride and applied to an expanded aluminum carrier. The tape is embossed with an innovative pattern for maximum conformability and minimal air pockets and offers excellent thermal, mechanical, environmental, and chemical properties. Our thermally conductive double-sided tape can bond heat sinks and thermal plates to components without the use of clips, screws, other mechanical fasteners, or additional thermal compounds and can be removed after the application without damage to the component.
