White Polyurethane Transparent Potting Compound Solution For Outdoor Lighting

UL94 V-1 White PU Potting for Automotive & Outdoor Lighting                                                                         

BZ-6118-8R is a two-component polyurethane encapsulant engineered for sealing, isolation, and protection of automotive lamps, outdoor LED fixtures, and modules. Offering rapid cure, UL94 V0/V1 flame rating, and high hardness, it streamlines production while ensuring mechanical ruggedness. RoHS and REACH compliant, it performs steadily from -40°C to 120°C, with thermal conductivity ≥0.5 W/m·k and surface resistivity ≥1.0×10¹³ Ω/sq for enduring reliability in demanding lighting environments.

Key Product Features

1. Flame Safety: UL94 V1-certified, limiting fire spread in enclosed or high-risk lighting systems.
2. Speedy Cure: Tack-free in 1.5±0.5 h, fully cured in 2.5±0.5 h at 25°C; oven cure ≤0.5 h at 60°C suits batch production.
3. Tough & Impact-Resistant: Shore D 52±10, tensile ≥4 MPa, elongation ≥45%, absorbing shock and vibration in transit or outdoor use.
4. Heat Dissipation: ≥0.5 W/m·k thermal conductivity aids cooling of high-power LED assemblies.
5. Simple Metering: 1:5 mix ratio (A:B) reduces errors and material waste, ideal for automated dispensers.
6. Regulatory Alignment: Meets RoHS, REACH, and UL94 V0/V1, satisfying global automotive and lighting standards.

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

1. Hardener: Typically 5KG/10KG/25KG/200KG metal or plastic drums.
2. Resin: Typically 25KG/200KG metal or plastic drums.
