UL94 V-0 Polyurethane Potting Compound For High-Temp Electronics

BZ-6805(BK) is a high-performance two-component polyurethane potting compound designed for insulation, flame retardancy, and waterproof protection of sensors, lighting fixtures, and automotive components operating in high-temperature environments. With moderate fluidity and deep penetration, it fully encapsulates sensitive circuits, providing robust defense against moisture, dust, and thermal stress. Certified UL94 V-0 flame retardant and compliant with RoHS/REACH regulations, this formula delivers reliable performance across -40℃ to 130℃, featuring ultra-high tensile strength (≥15 MPa) and low water absorption (≤0.5%) for long-term stability in critical applications.

Key Product Features

1. Multi-Color Customization: Available in black, beige, or white to match aesthetic and functional requirements of diverse electronic assemblies.
2. Ultra-High Electrical Insulation: Surface/volume resistivity ≥1.0×10¹⁴ Ω/sq/Ω·cm and breakdown voltage ≥15 kV/mm ensure superior component isolation.
3. Balanced Mechanical Strength: Shore A 82±10 hardness with ≥5 MPa tensile strength and ≥40% elongation, resisting vibration and impact in automotive and outdoor applications.
4. Efficient Processing: 3:10 mix ratio, 33±7 minute pot life, and fast curing (2-3 hour surface dry, 3-5 hour full cure at 25℃; 1±0.5 hour at 60℃).
5. Wide Temperature Stability: Operates reliably from -40℃ to 120℃, withstanding extreme cold in outdoor lighting and continuous heat in automotive systems.
6. Global Compliance: RoHS/REACH compliant, meeting international manufacturing standards for electronic and automotive industries.

Technical Parameters

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.
