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

Product Applications- Outdoor LED Lighting Fixtures: Seals and insulates street lamps, floodlights, and garden lights,
providing long-term protection against rain, dust, and UV exposure.
- Architectural LED Systems: Protects facade lighting, landscape lights, and decorative
fixtures in urban and commercial environments.
- Solar-Powered Lighting: Encapsulates LED drivers and charge controllers in off-grid solar
lighting systems, enhancing reliability in remote locations.
- Industrial LED Luminaires: Insulates high-bay lamps and warehouse lighting, withstanding
temperature fluctuations and mechanical stress.
- Marine LED Lighting: Provides waterproof protection for boat lights and underwater
fixtures in saltwater environments.
Directions for Use- Pre-potting Preparation: Calibrate scales, prepare potting tools, cleaning tools, check
machine settings, check vacuum pump force, etc.
- Product Pre-treatment: Place product on a level surface or fixture. Remove dust, clean,
degrease, and dry if necessary.
- 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.
- Mixing & Stirring: Manual operation requires thorough stirring or using electric
stirrers to ensure homogeneous mixing. Machine potting requires
sufficient stirring speed, adjust as needed.
- Uniform Potting: Manual operation should be done in small, multiple batches to
ensure uniformity. Machine potting should follow the programmed
path for quantitative dispensing.
- Inspection or Secondary Potting: After potting, visually inspect as needed. Perform touch-up,
bubble removal, or secondary potting if required.
- 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.
- Final Product Confirmation: Perform visual inspection and performance testing as required by
the customer.
Packing & Shipping & Storage- Hardener: Typically 5KG/10KG/25KG/200KG metal or plastic drums.
- Resin: Typically 25KG/200KG metal or plastic drums.
- Store and transport as a general chemical product.
- 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.
- 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.
