Product Overview for Silicone Potting Compound:
HN-8808B black potting compound is specially developed for high-heat-density electronic equipment. With a thermal conductivity of 0.5 W/m·K, it efficiently conducts heat away from heating components and greatly reduces their working temperature. The black formula also provides effective EMI shielding, solving both heat dissipation and EMC problems at the same time, and greatly prolongs the service life of electronic devices.

FAQ for Silicone Potting Compound:
1. Q: How does the thermal performance compare to competitors?
A: A thermal conductivity of 0.5 W/M·K is considered high for condensation-cure silicones, effectively addressing most high-heat applications. We can provide real application data for reference.
2. Q: Is it electrically conductive?
A: It is completely non-conductive. Its volume resistivity is on the order of 10¹⁴ Ω·cm, making it an excellent insulator.
3. Q: How is the adhesion to aluminum substrates? Can it pass thermal shock tests?
A: This is a core strength. Its elastomeric properties and optimized adhesion formula effectively absorb CTE mismatch between aluminum and components, passing -40°C to 125°C for 1000 cycles.
4. Q: Can this be used if my product's heat sink is plastic?
A: Yes, but confirm the plastic housing (e.g., PBT, Nylon) can withstand the long-term 200°C service temperature. We recommend compatibility and temperature testing first.
5. Q: Can you customize for higher thermal conductivity?
A: Yes. We have strong R&D capability and can offer customized formulas with thermal conductivity up to 1.0 W/M·K or higher. Please contact our engineers to discuss.
