BZ-6807(BK) is a UL94 V-0 polyurethane potting compound engineered specifically for automotive electronics, vehicle systems, and low-altitude aircraft platforms. It delivers certified fire safety alongside proven thermal durability, with a Relative Temperature Index (RTI) of 130°C and official UL Yellow Card recognition (QMFZ2.E352175).
1. V-0 at 1.5mm Thickness: Verified through vertical burn testing per UL Yellow Card QMFZ2.E352175 – an essential safeguard for ECUs, battery management systems, and UAV flight controllers where fire mitigation is non-negotiable.
2. 130°C Continuous Operation: Maintains dielectric and structural integrity under prolonged heat exposure, validated to automotive-grade thermal standards via QMFZ2.E352175.
3. Full-Spectrum Environmental Shielding: Integrates thermal cycling tolerance, UV stability, IP68-rated waterproofing, shock absorption, and high-voltage insulation – a complete armor for electronics in harsh operating environments.
4. Supply-Chain Ready Compliance: Fully aligns with RoHS, REACH, and IATF 16949 requirements, enabling friction-free adoption across global automotive and aerospace production networks.
