BZ-6805-1R is a versatile two-component polyurethane potting compound engineered for waterproofing, sealing, and insulation of electronic circuit boards, outdoor LED lighting fixtures, automotive components, and sensors. With moderate fluidity and balanced penetration, it fully encapsulates sensitive components, providing robust defense against moisture, dust, and mechanical stress. Compliant with RoHS/REACH regulations, this formula delivers reliable performance across -40℃ to 120℃, featuring ultra-high electrical resistivity (≥1.0×10¹⁴ Ω/sq) and low water absorption (≤0.5%) for long-term stability in harsh outdoor environments.
