Product Description

Fast-Cure Polyurethane Potting Compound for High-Efficiency Power Electronics Production                                               

BZ-6806-6-3R – a two-component polyurethane encapsulant designed for rapid insulation, sealing, and moisture protection in power supplies, industrial controllers, power tool PCBs, and EV converters. With UL94 V-0 rating, fast cure, and improved thermal conductivity, it boosts throughput and meets rigorous safety norms. RoHS-compliant, it performs reliably from -40°C to 120°C, with water absorption ≤0.5% for enduring high-power use.

Key Product Features

  1. UL94 V-0 certified: effectively curbs flame spread in critical assemblies.
  2. Rapid turnaround: cures in 2–6 hrs at 25°C, or ≤20 min at 60°C, suiting mass production.
  3. Simple 1:5 weight ratio: cuts waste, works with automated dispensers.
  4. Thermal conductivity ≥0.50 W/m·k: dissipates heat to enhance component longevity.
  5. High insulation strength: breakdown voltage ≥15 kV/mm, surface resistivity ≥1.0×10¹¹ Ω/sq.
  6. Balanced flexibility: Shore A 73±10, absorbs vibration and thermal stress.
  7. Globally compliant: meets RoHS and UL94 V-0, easing international market entry.

Rapid Cure Polyurethane Potting Compound Thermal Conductive For Electronics 6806-6-3R

Product Applications

  1. High-Volume Power Supplies: Encapsulates consumer electronics chargers, industrial power inverters, and server power units, supporting rapid production lines.
  2. New Energy Vehicle Components: Insulates battery management systems (BMS), on-board chargers, and DC-DC converters, withstanding extreme temperature fluctuations and mechanical vibration.
  3. Industrial Controllers: Seals PLCs, motor drives, and power tool control boards, protecting against dust, moisture, and harsh manufacturing environments.
  4. Renewable Energy Systems: Protects solar inverters and wind turbine controllers, ensuring long-term reliability in outdoor installations with fire safety requirements.
  5. Telecommunications Infrastructure: Encapsulates base station power modules and signal processing units, enhancing durability in enclosed telecom cabinets.


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 & Shipping & Storage

  1. Hardener: Typically 5KG/10KG/25KG/200KG metal or plastic drums.
  2. Resin: Typically 25KG/200KG metal or plastic drums.
  3. Store and transport as a general chemical product.
  4. Store sealed, protected from light at room temperature. Shelf life varies from 6 to 12 months depending on packaging; please refer to the expiry date on the shipping package.
  5. When temperature drops to 15°C or lower, the hardener or resin should be stored in a warm place or heated before use for potting. Specific heating recommendations depend on the temperature drop; please communicate and consult with us.
