Customizable-Curing Polyurethane Potting Compound For Outdoor LED Lighting

BZ-6805-3R-K is a two-component polyurethane system formulated for waterproofing, sealing, and insulating outdoor LED fixtures. Featuring tunable curing profiles and multiple color options, it adapts to varied production needs while delivering robust protection from -40°C to 120°C. With ultra-high resistivity (≥1.0×10¹⁴ Ω/sq) and low water uptake (≤0.5%), it ensures lasting reliability in harsh exterior conditions. RoHS/REACH compliant.

Key Product Features

1. Color Versatility – Available in beige, black, white, or grey to suit design and functional preferences.
2. Tailored Curing – Pot life 14–28 min, cure time 2–4h at 25°C (adjustable via temperature/process), enabling flexible production pacing.
3. Exceptional Insulation – Surface/volume resistivity ≥1.0×10¹⁴ Ω/sq/Ω·cm and breakdown voltage ≥15 kV/mm for secure component isolation.
4. Robust Mechanics – Shore A 82±8 hardness, tensile strength ≥5 MPa, and elongation ≥40% to withstand outdoor vibration and impact.
5. Production Efficiency – 3:10 mix ratio with rapid heat cure (1±0.5h at 60°C) supports high-throughput manufacturing.
6. Globally Certified – Meets RoHS/REACH standards for international electronics markets.

Technical Parameters

Product Applications

1. Outdoor LED Lighting Fixtures: Seals and insulates street lamps, floodlights, and garden lights, providing long-term protection against rain, dust, and UV exposure.
2. Architectural LED Systems: Protects facade lighting, landscape lights, and decorative fixtures in urban and commercial environments.
3. Solar-Powered Lighting: Encapsulates LED drivers and charge controllers in off-grid solar lighting systems, enhancing reliability in remote locations.
4. Industrial LED Luminaires: Insulates high-bay lamps and warehouse lighting, withstanding temperature fluctuations and mechanical stress.
5. Marine LED Lighting: Provides waterproof protection for boat lights and underwater fixtures in saltwater environments.

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.
