BZ-6806-6-3R is a two-component polyurethane encapsulant engineered for rapid insulation, sealing, and moisture protection in power supplies, industrial controllers, power tool PCBs, and EV converters. Featuring UL94 V-0 rating, fast cure, and enhanced thermal conductivity, it boosts production efficiency while meeting stringent safety standards. RoHS-compliant, it operates reliably from -40°C to 120°C, with water absorption ≤0.5% for long-term high-power durability.

Key Product Features

1. Flame-Retardant Certified: UL94 V-0 rating effectively inhibits flame spread in critical assemblies.
2. Ultra-Fast Cure: Cures in 2–6 hrs at 25°C, or ≤20 min at 60°C—ideal for high-volume production.
3. Simple Metering: 1:5 weight ratio minimizes waste and works seamlessly with automated dispensing systems.
4. Thermally Conductive: ≥0.50 W/m·K thermal conductivity for efficient heat dissipation and extended component life.
5. High Dielectric Strength: Breakdown voltage ≥15 kV/mm; surface resistivity ≥1.0×10¹¹ Ω/sq.
6. Vibration-Damping Flexibility: Shore A 73±10, absorbing mechanical shock and thermal expansion.
7. Globally Accepted: Meets RoHS and UL94 V-0, simplifying international compliance.

Directions for Use

1. Pre-potting Preparation: Calibrate scales, prepare potting tools, cleaning tools, check machine settings, check vacuum pump force, etc.
2. Product Pre-treatment: Place product on a level surface or fixture. Remove dust, clean, degrease, and dry if necessary.
3. Accurate Proportioning: Manual operation requires precise mixing according to the specified ratio and recording. Machine potting requires calibrated ratios and first-article confirmation is recommended.
4. Mixing & Stirring: Manual operation requires thorough stirring or using electric stirrers to ensure homogeneous mixing. Machine potting requires sufficient stirring speed, adjust as needed.
5. Uniform Potting: Manual operation should be done in small, multiple batches to ensure uniformity. Machine potting should follow the programmed path for quantitative dispensing.
6. Inspection or Secondary Potting: After potting, visually inspect as needed. Perform touch-up, bubble removal, or secondary potting if required.
7. Curing: Allow the potted and inspected products to cure at room temperature or with heat assistance (recommended 60°C if needed), according to product and process requirements.
8. Final Product Confirmation: Perform visual inspection and performance testing as required by the customer.

Packing

1. Hardener: Typically 5KG/10KG/25KG/200KG metal or plastic drums.
2. Resin: Typically 25KG/200KG metal or plastic drums.
