Thermal PU PCB Potting Compound Resin IP67 Rated 10KG 20KG BZ-3318

Fexible Transparent PU Potting Compound With Excellent Low Temperature Tolerance

3318-1-K PU potting compound is a transparent polyurethane material with exceptional flexibility, enabling flexible LED light strips to be installed in curved configurations. It exhibits strong adhesion to LED chips and flexible printed circuits (FPCs), providing up to 2 years of anti-yellowing performance for the light strips. This transparent polyurethane is specifically designed for LED flexible light strips and lighting products, while also achieving IP67-rated waterproof performance. 

1. It has good weather resistance and UV resistance, and does not yellow within 2 years.
2. The product meets environmental requirements such as RoHS/REACH and is easy and fast to export.
3. Exhibits excellent flexibility and bending resistance, with a tensile elongation rate of up to 200%.
4. Two-component transparent weather-resistant polyurethane features excellent fluidity, with a streamlined operation process and easy dispensing, making it suitable for both manual and mechanical applications.

1. Sensor: Transparency, flexible, resistant to high and low temperature shocks, suitable for various application scenarios.
2. LED Flexible Strip Light: With excellent transparency and heat resistance, the LED flexible light strip remains flexible even at low temperatures without hardening. These features enable it to withstand harsh installation and operating conditions.

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.

1. Hardener: Typically 5KG/ 10KG / 20KG/ 200KG metal or plastic drums.
2. Resin: Typically 5KG/ 10KG / 20KG / 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.
