Fast-Curing Polyurethane Potting Compound for Filtration Systems
BZ-6902-1 is a high-performance two-component polyurethane encapsulant engineered for rapid sealing and structural bonding of air, oil, and high-efficiency filters. It cures fully in 2.5±0.5 hours at 25℃ (or ≤15 minutes with 60℃ heat), delivering high elongation (≥50%) and strong electrical insulation (breakdown voltage ≥20 kV/mm). This RoHS-compliant formulation offers low moisture uptake (≤0.5%) and robust adhesion to metals, plastics, and filter media, ensuring lasting reliability in tough industrial settings from -40℃ to 100℃.
Key Product Features
Fast Cure: Fully cures in 2.5±0.5 h at 25°C; accelerates to ≤15 min at 60°C for high-throughput production.
Simple Metering: 1:2 mix ratio cuts errors and waste, compatible with automated dispensers.
Resilient Flexibility: Shore A 65±8, elongation ≥50%, absorbs shock and accommodates thermal expansion.
High Dielectric Strength: Breakdown voltage ≥20 kV/mm, volume resistivity >1.0×10¹¹ Ω·cm for reliable isolation.
Versatile Adhesion: Forms durable, leak-tight bonds to metals, plastics, and various filter media.
Eco-Conscious: Fully RoHS-compliant, meeting global environmental standards.
Controllable Pot Life: 7±3 min at 25°C, adjustable for seasonal temperature variations.

Product Applications
Air Filters: Seals automotive cabin filters, industrial HVAC filters, and cleanroom air filters, preventing air leakage and enhancing filtration efficiency.
Oil Filters: Bonds filter media to metal end caps in automotive and industrial oil filters, ensuring structural integrity under high-pressure conditions.
High-Efficiency Filters: Encapsulates HEPA and ULPA filter frames, providing airtight seals and mechanical stability in critical environments like hospitals and data centers.
Filter Control Electronics: Insulates sensor modules and control circuits in smart filter systems, protecting against dust, moisture, and electrical interference.
Industrial Filtration Systems: Seals hydraulic filters, fuel filters, and water treatment filters, withstanding exposure to harsh chemicals and temperature fluctuations.
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
Hardener: Typically 5KG/10KG/20KG/200KG metal or plastic drums.
Resin: Typically 10KG/20KG/200KG metal or plastic drums.
