Product Description

Customizable-Curing Polyurethane Potting Compound For Outdoor LED Lighting                                                              

BZ-6805-3R-K is a versatile two-component polyurethane potting compound optimized for waterproofing, sealing, and insulation of outdoor LED lighting fixtures. With adjustable curing times and multi-color options, it balances workability and performance to meet diverse manufacturing requirements. Compliant with RoHS/REACH regulations, this formula delivers reliable protection across -40℃ to 120℃, featuring ultra-high electrical resistivity (≥1.0×10¹⁴ Ω/sq) and low water absorption (≤0.5%) for long-term stability in harsh outdoor environments.

Key Product Features

  1. Multi-Color Customization: Available in beige, black, white, or grey to match aesthetic and functional requirements of LED lighting fixtures.
  2. Adjustable Curing Speed: Pot life 14-28 minutes and curing time 2-4 hours at 25℃ (adjustable via process/temperature), ideal for flexible production lines.
  3. Ultra-High Electrical Insulation: Surface/volume resistivity ≥1.0×10¹⁴ Ω/sq/Ω·cm and breakdown voltage ≥15 kV/mm ensure superior component isolation.
  4. Balanced Mechanical Strength: Shore A 82±8 hardness with ≥5 MPa tensile strength and ≥40% elongation, resisting vibration and impact in outdoor installations.
  5. Efficient Processing: 3:10 mix ratio with fast heat curing (1±0.5 hour at 60℃), supporting high-volume manufacturing.
  6. Global Compliance: RoHS/REACH compliant, meeting international standards for outdoor electronic assemblies.

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 & 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.
