Polyurethane Electrical Reenterable Potting Compound Gel 6210 UL94V-0 6210
UL94V-0 Polyurethane Potting Compound for Lighting & Electronics
Product Description
BZ-6210 is a two-component polyurethane encapsulant designed for insulation, sealing, and protection of lighting fixtures, electronics, power supplies, and control boards. Its superior flow and deep-fill capability ensure complete coverage of complex assemblies, offering reliable resistance against moisture, dust, and mechanical impact. Rated UL94 V-0, RoHS/REACH-compliant, and halogen-free, this formulation performs steadily from -40℃ to 120℃, with thermal conductivity ≥0.5 W/m·k and water absorption ≤0.5%, ensuring long-term durability in demanding environments.
Key Product Features
- UL94 V-0 Certified: Meets stringent flame-retardant standards, minimizing fire spread in enclosed or critical applications.
- Broad Thermal Range: Stable performance across -40℃ to 120℃, withstanding extreme temperature swings.
- High Insulation Strength: Surface/volume resistivity ≥1.0×10¹² Ω/sq/Ω·cm and breakdown voltage ≥16 kV/mm, preventing leakage and interference.
- Flexible Toughness: Shore A 45±10 hardness delivers vibration damping and thermal expansion accommodation without cracking.
- Production-Friendly: 1:4 mix ratio, 25±10 min pot life, and dual cure (ambient or 60°C accelerated) support both hand and automated lines.
- Green Compliance: Halogen-free and fully RoHS/REACH-aligned with global environmental standards.

Product Applications
- LED Lighting Drivers: Provides thermal management and fire safety for indoor/outdoor LED fixtures.
- Power Supply Units: Seals AC/DC power supplies, inverters, and chargers against moisture and dust.
- Home Appliance Control Boards: Insulates sensitive circuits in refrigerators, HVAC systems, and washing machines.
- Industrial Electronics: Protects PLCs, motor controllers, and sensors from vibration and chemical exposure.
- Custom Assemblies: Versatile sealing for medical devices, automotive electronics, and IoT sensors with strict safety requirements.
Directions for Use
- Pre-potting Preparation: Calibrate scales, prepare potting tools, cleaning tools, check machine settings, check vacuum pump force, etc.
- Product Pre-treatment: Place product on a level surface or fixture. Remove dust, clean, degrease, and dry if necessary.
- 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.
- Mixing & Stirring: Manual operation requires thorough stirring or using electric stirrers to ensure homogeneous mixing. Machine potting requires sufficient stirring speed, adjust as needed.
- Uniform Potting: Manual operation should be done in small, multiple batches to ensure uniformity. Machine potting should follow the programmed path for quantitative dispensing.
- Inspection or Secondary Potting: After potting, visually inspect as needed. Perform touch-up, bubble removal, or secondary potting if required.
- 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.
- Final Product Confirmation: Perform visual inspection and performance testing as required by the customer.
Packing
- Hardener: Typically 5KG/10KG/25KG/200KG metal or plastic drums.
- Resin: Typically 25KG/200KG metal or plastic drums.
