Product Description

BZ-6807(BK) is a high-performance polyurethane potting compound with UL94 V-0 rating (1.5mm), engineered for automotive electronics, components, and low-altitude aircraft systems. It meets stringent industry demands for fire safety and thermal durability, featuring an RTI of 130°C for sustained heat resistance, with UL Yellow Card Certification No. QMFZ2.E352175.

Key Product Features

1. UL94 V-0 at 1.5mm: Passes rigorous vertical flame tests; trusted for automotive ECUs, battery management systems (BMS), and UAV electronic components where fire protection is critical.
2. RTI 130°C Thermal Endurance: Preserves mechanical and dielectric integrity under prolonged heat exposure, as certified per UL Yellow Card QMFZ2.E352175.
3. All-Environment Protection: Combines temperature tolerance, UV resistance, IP68 waterproofing, shock/vibration damping, and high dielectric strength for reliable performance in extreme conditions.
4. Global Regulatory Ready: Fully compliant with RoHS, REACH, and IATF 16949, ensuring smooth integration into international automotive and aerospace supply chains.   

Technical Parameters 

Product Applications

1. Automotive Electronics – High electrical performance, vibration resistance, V0 flame retardancy, thermal stability, and reliability.
2. Low-Altitude Aircraft – Low density enables lightweight design; combines flexibility with IP68 waterproofing.
3. Sensors – Low density, V0 rating, low dielectric constant, and low-temperature tolerance.
4. Industrial Controllers & Boards – Excellent heat resistance (RTI 130 compliant), high thermal conductivity and dissipation, plus V0 fire protection.
5. Other Electronics – V0 flame retardancy, UL Yellow Card, RTI 130 compliance, and robust electrical/mechanical properties to meet high-performance material demands across most applications.

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.
