BZ-6805-3R-K is a versatile two-component polyurethane potting compound optimized for waterproofing, sealing, and insulation of outdoor LED lighting fixtures. With adjustable curing times and multi-color options, it balances workability and performance to meet diverse manufacturing requirements. Compliant with RoHS/REACH regulations, this formula delivers reliable protection 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.
