Summary of THERMALLY CONDUCTIVE 1-PART EPOXY ADHESIVE
This thermally conductive 1-part epoxy adhesive is a heat-cured, off-white thixotropic paste that bonds well to many substrates. It requires no mixing, has unlimited working time, and stores at room temperature. It cures to a hard, electrically insulating, thermally conductive polymer (0.8 W/m·K) with high compressive strength and resistance to humidity, salt water, mild bases, and aliphatic hydrocarbons. Typical cure schedules are 2 hours at 80 °C or 30 minutes at 120 °C. It is recommended for attaching heat sinks to LEDs, CPUs, and other heat-generating components.
Parts used in the Thermally Conductive 1-Part Epoxy Adhesive Project:
- Thermally conductive 1-part epoxy adhesive (off white thixotropic paste)
