Description
A3000 is designed for repeated, reuse after disassembly of parts. Particularly good for sliding surfaces together whilst making electric isolation and achieving an excellent thermal interface. The material is constructed from a thermally conductive non-silicon structural adhesive and a high dielectric strength thermally conductive polymer in combination. The adhesive is bonded to one surface permanently whilst the polymer is able to connect the other surface thermally maintaining a high level of electrical isolation. The parts can be cleanly disassembled with the A3000 staying on one side whilst the polymer side separates cleanly. The A3000 is designed to be re-used.
A3000 thermally transfers heat across 2 surfaces maintaining high voltage electrical isolation whilst achieving mechanical wear resistance. Ideal for surfaces that slide together or parts that need to be unassembled leaving the thermal interface intact on one side whilst the other side is removed cleanly.
Benefits
- The adhesive is permanently bonded to a variety of metal surfaces
- Robust and tested in a customer application to withstand 50g loadings in Electric vehicle crash
- Simple to handle and apply
Features
- Constructed from thermal conductive adhesive and a thermally conductive polyimide film on one side
- Constructed from thermal conductive adhesive and a thermally conductive polyimide film on one side
- Provides heat exchange between component and cooling mechanism
Recommended Uses
- Mounting high & mid-power LED modules to a heatsink
- To provide a fast and consistent method of attaching power components to a heat sink
- Electric vehicle cooling plates, wedge-lock applications
- A3000 adhesive is NOT suitable for painted or powder coated surfaces
