It cures at room temperature or with heat acceleration, generating no reaction by-products during curing. The cured silicone remains flexible with low internal stress, featuring stable electrical insulation, excellent thermal conductivity ≥3.0 W\/(m·K), and easy removal for circuit board maintenance and repair.\u003c\/p\u003e\n\u003cp\u003eThis AB silicone potting gel is designed for long-term encapsulation and protection of sensitive electronic components, effectively transferring heat from power modules to heat sinks while sealing PCBs against moisture, dust, vibration and thermal shock.
