UV Resistant Polyurethane PU Potting Compound Glue Material For LED Light Strip

(Cruical)UV-resistant High-performance PU Potting Compound For LED Light Strip                                                                                                          

Product Description

BZ-3329-1 PU Potting Compound is a yellowing-resistant transparent polyurethane material specifically developed for flexible LED lighting applications. This outdoor-grade material offers up to five years of yellowing resistance while maintaining excellent flexibility and durability against repeated bending. It provides effective waterproof sealing protection for flexible LED strips and flexible displays currently available on the market, preventing moisture ingress and water damage from compromising LED chips and FPC (Flexible Printed Circuit) boards. Furthermore, thanks to its superior weatherability and physical properties, this material ensures the long-term stable operation of such LED flexible lighting solutions in outdoor and harsh environments.

Key Product Features

1. Two-component polyurethane system featuring a user-friendly processing procedure and moderate flowability.
2. Compliant with RoHS and environmental regulations.
3. Can be heated to accelerate curing, offering efficient curing performance.
4. Excellent weatherability and UV resistance, providing up to 5 years of outdoor service life; 
5. Outstanding flexibility and bend resistance, effectively protecting LEDs and FPCs.

Technical Parameters 

Product Applications

1. LED Linear Lights: High transparency, wide operating temperature range of -40 to 85°C, and 5-year yellowing resistance enable the lights to perform in more demanding environments.
2. LED Flexible Displays: The high-transparency potting material provides full protection for the entire display while allowing protected bending during installation.
3. Sensors: Soft and low-stress characteristics offer effective protection for internal electronic components.
4. LED Flexible Strips: With a Shore A hardness of 55, 90°bendability, and 110% elongation at break, the strips support more versatile installation methods.

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 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 5KG/ 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.
