Clear Polyurethane Electrical Potting Compound Glue For Mart Metering ODM BZ

Moderate-Hardness Transparent Polyurethane For Semi-Outdoor Smart Metering                                                                

Product Description

BZ-2318-3W is a two-component polyurethane encapsulant optimized for semi-outdoor smart metering applications, offering balanced hardness, reliable weather resistance, and low-stress protection for electronic components and LCD displays. With a 1:1 weight mix ratio and Shore A hardness of 70±10, it provides robust waterproofing, strong adhesion to meter housings and circuit boards, and long-term stability in semi-exposed environments. This adhesive complies with RoHS and REACH standards, making it suitable for export-oriented smart metering products.

Key Product Features

1. Balanced Hardness & Flexibility: Shore A hardness of 70±10 strikes an ideal balance between structural support and shock absorption, protecting delicate components while resisting mechanical damage in semi-outdoor installations.
2. Enhanced UV Resistance: Withstands 150 hours of UV exposure (GB/T14522-2008, 4级) without significant degradation, ensuring reliable performance in covered outdoor and semi-underground installations.
3. Extended Shelf Life: 6-month storage period when sealed and protected from light, reducing inventory turnover costs and improving supply chain efficiency.
   Improved Process Efficiency: Longer pot life (20–30 minutes at 25°C) allows for more flexible production scheduling, reducing material waste and improving yield in both manual and automated manufacturing.
4. Excellent Adhesion: Forms strong bonds with metals, plastics, and circuit boards, eliminating the need for additional sealing components and reducing assembly complexity.
5. Low Density & Lightweight: 1.01–1.02 g/cm³ component density reduces overall meter weight, simplifying installation and transportation in urban and rural environments.

Technical Parameters 

Product Applications

1. Semi-Outdoor Water Meters: Encapsulates control circuits and LCD displays in smart water meters installed in covered outdoor areas, providing protection against dust, moisture, and UV radiation.
2. Electricity Meter Sealing: Bonds meter housings and seals terminal blocks in semi-outdoor electricity meters, preventing water ingress and ensuring safe operation in high-humidity environments.
3. Gas Module Protection: Encapsulates pressure sensors and control modules in semi-outdoor gas meters, protecting against corrosion and mechanical damage in underground and above-ground installations.
4. Industrial Flow Meters: Seals flow sensors and control circuits in industrial metering systems, providing reliable protection against dust, moisture, and temperature fluctuations in factory environments.
5. Export-Oriented Meters: Complies with international environmental standards (RoHS, REACH), making it suitable for smart meters destined for global markets with varying climate conditions.

Directions for Use

Pre-potting Preparation: Calibrate scales, prepare potting tools, cleaning tools, check machine settings, check vacuum pump force, etc. 

Product Pre-treatment: Place product on  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 metal or plastic drums.

Resin: Typically 5KG/ 10KG / 20KG 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.
