UL94 -V1 White Polyurethane Potting Compound For Automotive & Outdoor Lighting

BZ-6118-8R is a high-performance two-component polyurethane potting compound designed for isolation, sealing, and protection of automotive lamps, outdoor LED fixtures, and LED modules. With fast curing times, UL94 V0/V1 flame retardancy, and high hardness, it balances production efficiency with mechanical durability. Compliant with RoHS and REACH regulations, this formula delivers reliable performance across -40℃ to 120℃, featuring excellent thermal conductivity (≥0.5 W/m·k) and ultra-high electrical resistivity (≥1.0×10¹³ Ω/sq) for long-term stability in harsh lighting applications.

Key Product Features

1. UL94 V1 Flame Retardancy: Achieves strict fire safety certification, inhibiting flame spread for enclosed or high-risk lighting assemblies.
2. Fast Curing: Surface drying in 1.5±0.5 hours and full cure in 2.5±0.5 hours at 25℃; heat curing (≤0.5 hours at 60℃) supports high-volume production.
3. High Hardness & Durability: Shore D 52±10 hardness with ≥4 MPa tensile strength and ≥45% elongation, resisting impact and vibration in automotive and outdoor environments.
4. Enhanced Thermal Conductivity: ≥0.5 W/m·k, improving heat dissipation in high-power LED components.
5. 1:5 Mix Ratio: Simplifies proportioning and reduces waste, ideal for automated dispensing systems.
6. Global Compliance: RoHS and REACH compliant with UL94 V0/V1 certification, meeting international safety standards for automotive and lighting industries.

Technical Parameters

Product Applications

1. Automotive Lighting: Encapsulates headlamps, taillights, and interior lighting modules, withstanding vibration and temperature fluctuations.
2. Outdoor LED Fixtures: Seals street lamps, floodlights, and garden lights, providing long-term protection against rain, dust, and UV exposure.
3. LED Modules: Protects high-power LED arrays and driver circuits, enhancing thermal management and reliability.
4. Architectural Lighting: Insulates facade lighting, landscape lights, and decorative fixtures in urban and commercial environments.
5. Industrial Lighting: Encapsulates high-bay lamps and warehouse lighting, withstanding mechanical stress and harsh conditions.

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.
