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 potting compound engineered for insulation, sealing, and protection of lighting products, electronics, electrical appliances, power supplies, and control boards. With excellent fluidity and deep penetration capabilities, it ensures full encapsulation of intricate components, providing robust defense against moisture, dust, and mechanical stress. Certified with UL94 V-0 flame retardancy and compliant with RoHS/REACH regulations, this halogen-free formula delivers reliable performance across -40℃ to 120℃, featuring high thermal conductivity (≥0.5 W/m·k) and low water absorption (≤0.5%) for long-term stability in harsh operating environments.

Key Product Features

1. UL94 V-0 Flame Retardancy: Achieves strict fire safety certification, inhibiting flame spread for enclosed or high-risk applications.
2. Wide Temperature Stability: Operates reliably from -40℃ to 120℃, maintaining consistent performance across extreme thermal conditions.
3. Superior Electrical Insulation: High surface/volume resistivity (≥1.0×10¹² Ω/sq/Ω·cm) and breakdown voltage (≥16 kV/mm) prevent short circuits and signal interference.
4. Flexible & Durable Bonding: Shore A 45±10 hardness balances flexibility and strength, absorbing vibration and accommodating thermal expansion without cracking.
5. Efficient Processing: 1:4 mix ratio, 25±10 minute pot life, and dual curing options (room temp or 60℃ acceleration) suit manual/automated production lines.
6. Global Compliance: RoHS/REACH compliant with halogen-free formulation, meeting international manufacturing standards.

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.
5. Custom Assemblies: Versatile sealing for medical devices, automotive electronics, and IoT sensors with strict safety requirements.

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.
