High-Rigidity Polyurethane Potting Compound for Filter Applications
BZ-6906-K is a two-component polyurethane system tailored for structural bonding and sealing of high-efficiency, air, and oil filters. It cures rapidly at room temperature (full cure in 2±1 hours), delivers high Shore D hardness (68±8), and offers excellent electrical insulation (breakdown voltage ≥20 kV/mm). With stable performance from -40°C to 120°C, low water absorption (≤0.5%), and strong adhesion to metals, plastics, and filter media, it ensures durable, leak-proof sealing in harsh industrial settings. RoHS compliant.
Key Product Features
Fast Curing- Full cure in 2±1h at 25°C, or ≤45min with 60°C heating for flexible scheduling.
Simple Mixing – 1:2 ratio reduces waste and supports automated dispensing.
High Stiffness – Shore D 68±8 hardness with ≥35% elongation, ideal for structural filter bonding.
Broad Thermal Range – Reliable from -40°C to 120°C for extreme conditions.
Eco-Compliant – Meets RoHS standards for global industrial use.
Tenacious Adhesion – Bonds firmly to metal, plastic, and filter media, ensuring long-term seal integrity.

Product Applications
High-Efficiency Filters: Structural bonding of HEPA/ULPA filter frames and media, providing airtight seals and mechanical stability in cleanrooms, hospitals, and data centers
Air Filters: Seals automotive cabin filters and industrial HVAC filters, enhancing filtration efficiency by eliminating air bypass around filter edges
Oil Filters: Bonds filter media to metal end caps in automotive and industrial oil filters, withstanding high-pressure fluid flow and vibration
Industrial Filtration Systems: Seals hydraulic filters, fuel filters, and water treatment filters, resisting chemical exposure and temperature fluctuations
Filter Control Modules: Encapsulates sensor circuits and control electronics in smart filter systems, protecting against dust, moisture, and electrical interference
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/20KG/200KG metal or plastic drums.
Resin: Typically 10KG/20KG/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.
