BZ-6210 is a two-component polyurethane potting material for insulating, sealing, and protecting LED fixtures, power supplies, control boards, and other electronics. Its optimized flow ensures deep penetration and full encapsulation of complex shapes, providing reliable resistance to moisture, dust, and mechanical stress. Rated UL94 V-0 and fully RoHS/REACH-compliant and halogen-free, it operates from –40°C to 120°C, with thermal conductivity ≥0.5 W/m·K and water absorption ≤0.5% for long-term durability in demanding environments.

Key Product Features

1.V-0 Flame Rating: Meets rigorous fire-safety criteria, reducing combustion risk in confined or safety-sensitive installations.
2.Wide-Temperature Capability: Maintains integrity across –40°C to 120°C, accommodating severe thermal cycling.
3.Superior Dielectric Properties: Resistivity ≥1.0×10¹² Ω·cm and breakdown voltage ≥16 kV/mm guard against current leakage and signal interference.
4.Resilient Flexibility: Shore A 45±10 provides cushioning against vibration and allows for thermal movement without cracking.
5.Process Versatility: 1:4 ratio, pot life 25±10 min; cures at ambient temperature or accelerated at 60°C, suitable for manual dispensing or automated lines.
6.Eco-Friendly Formulation: Halogen-free with full RoHS/REACH conformity, aligning with worldwide sustainability directives..

Technical Parameters

Product Applications

1. LED Lighting Drivers: Provides thermal management and fire safety for indoor/outdoor LED fixtures.
2. Power Supply Units: Seals AC/DC power supplies, inverters, and chargers against moisture and dust.
3. Home Appliance Control Boards: Insulates sensitive circuits in refrigerators, HVAC systems, and washing machines.
4. Industrial Electronics: Protects PLCs, motor controllers, and sensors from vibration and chemical exposure.

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.
