UL94 V0 Polyurethane Potting Compound for Home Electronics Protection
Product Description
BZ-6801 is a two-component, halogen-free polyurethane potting compound optimized for home electronics control systems. Boasting a transparent appearance, repairable properties, and low-stress curing, it combines excellent fluidity, easy pouring, and robust environmental protection. With official UL Yellow Card Certification No. QMFZ2.E352175 for UL94 V0 flame retardancy (3.0mm thickness), it operates reliably across -60℃ to 120℃, providing IP67 waterproof sealing and high dielectric strength while complying with RoHS and REACH regulations. Its 1:1 weight mix ratio is highly user-friendly for both manual and automated potting processes, making it ideal for safeguarding sensitive electronics in high-humidity and temperature-fluctuating home environments.
Key Product Features
UL94 V0 Flame Retardancy (3.0mm thickness) Validated by UL Yellow Card QMFZ2.E352175, passes rigorous vertical burn tests to ensure critical fire safety for home electronics control boards.
Wide Temperature Adaptability Maintains stable performance across -60℃ to 120℃, withstanding extreme cold and high heat to ensure reliability in diverse home environments.
IP67 Waterproof & Dustproof Protection Delivers robust sealing against water immersion (up to 1m for 30 minutes) and dust ingress, ideal for bathroom and kitchen electronics. Low water absorption (≤0.5%) prevents moisture-related failures.
Transparent & Repairable Design Clear formulation enables visual inspection of internal components post-curing, while its repairable properties allow for easy component replacement and maintenance, reducing product downtime and repair costs.
Low-Stress Curing Minimizes internal stress on electronic components during the curing process, preventing damage to sensitive chips and solder joints and ensuring long-term operational reliability.
User-Friendly 1:1 Weight Mix Ratio Simplifies measurement and mixing for both manual and automated potting operations, reducing operational errors and improving efficiency. Offers a generous pot life of 28-36 minutes at 25℃, with fast room-temperature curing (surface dry in 3-5 hours, full cure in 4-6 hours). High fluidity ensures deep penetration into complex electronic assemblies.
Global Compliance Meets RoHS, REACH, and halogen-free standards, ensuring seamless integration into international home electronics supply chains.

Product Applications
Washing Machine Control Boards: Protects against water splashes and electrical short circuits, ensuring stable operation in high-humidity laundry environments.
Dishwasher Control Systems: Withstands high-temperature steam and detergent corrosion, maintaining reliable performance during repeated wash cycles.
Smart Toilet Control Panels: IP67 waterproof sealing prevents water damage, supporting long-term use in bathroom environments.
Robot Vacuum Control Modules: Vibration resistance and wide temperature adaptability ensure stable navigation and cleaning performance across home surfaces.
General Home Electronics: Versatile protection for air conditioner controllers, smart lighting drivers, and small appliance power supplies, extending product lifespan.
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.
