High Resistance Clear Polyurethane Potting Compound Epoxy For Outdoor Electronics 6805-1R

High-Resistance Polyurethane Potting Compound For Outdoor Electronics                                                                       

Product Description

BZ-6805-1R is a two-component polyurethane potting system formulated for waterproofing, sealing, and insulating circuit boards, outdoor LED fixtures, automotive parts, and sensors. Its moderate flow and balanced penetration ensure full encapsulation of sensitive components, offering reliable protection against moisture, dust, and mechanical stress. RoHS/REACH compliant, it performs steadily from -40°C to 120°C, with ultra-high electrical resistivity (≥1.0×10¹⁴ Ω/sq) and low water absorption (≤0.5%) for enduring stability in demanding outdoor settings.

Key Product Features

1. Customizable Colors: Available in black, beige, or white to suit design and functional needs.
2. Superior Insulation: Surface/volume resistivity ≥1.0×10¹⁴ Ω/sq/Ω·cm and breakdown voltage ≥15 kV/mm ensure robust component protection.
3. Balanced Mechanics: Shore A 82±10 hardness, tensile strength ≥5 MPa, and elongation ≥40% withstand vibration and impact.
4. Process-Friendly: Mix ratio 3:10, pot life 33±7 minutes; cures at 25°C (surface dry in 2–3h, full cure in 3–5h) or 60°C (1±0.5h).
5. Broad Thermal Range: Reliable operation from -40°C to 120°C, handling both severe cold and sustained heat.
6. Globally Certified: Meets RoHS/REACH standards for electronics and automotive manufacturing..

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. Automotive Electronic Components: Protects sensors, control modules, and wiring harnesses from vibration, temperature fluctuations, and road debris.
3. Industrial Circuit Boards: Encapsulates PLCs, motor controllers, and power supplies, enhancing reliability in manufacturing and renewable energy systems.
4. Smart City Sensors: Provides environmental sealing for traffic sensors, weather stations, and air quality monitors in urban and remote locations.
5. Marine Electronics: Insulates navigation systems, communication equipment, and battery management systems 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.
