Flexible-Cure PU Potting for Outdoor LED Fixtures 6805-3R-K

BZ-6805-3R-K is a two-component polyurethane system developed for waterproofing, sealing, and insulating outdoor LED luminaires. With adjustable curing behavior and multiple color choices, it accommodates diverse production workflows while offering robust protection across -40°C to 120°C. Ultra-high resistivity (≥1.0×10¹⁴ Ω/sq) and low moisture absorption (≤0.5%) ensure long-term dependability in severe exterior environments. Fully RoHS/REACH compliant.

Key Product Features

1.Color Versatility: Available in beige, black, white, or grey to match aesthetic and functional requirements.
2.Tailored Curing: Pot life 14–28 min, ambient cure 2–4h at 25°C (adjustable through temperature/process variables), enabling flexible production scheduling.
3.Exceptional Insulation: Surface/volume resistivity ≥1.0×10¹⁴ Ω/sq/Ω·cm and breakdown voltage ≥15 kV/mm for reliable component isolation.
4.Robust Mechanics: Shore A 82±8 hardness, tensile ≥5 MPa, and elongation ≥40% to endure outdoor shock and vibration.
5.Production Efficiency: 3:10 mix ratio with accelerated heat cure (1±0.5h at 60°C) supports high-volume output.
6.Globally Certified: Conforms to RoHS/REACH standards for worldwide electronics market access.

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.
