Technical Parameters

Product Applications

1. LED flexible light strip: 45A Shore hardness, 90°C bendability, 100% elongation at break, enabling versatile installation.
2. LED strip light: Excellent flexibility and LED protection, -40°C to 85°C range, suitable for harsh environments.
3. LED display: Flexible encapsulation protects the full display, enables flexible installation, and ensures a smooth surface for tight glass-substrate adhesion.
4. Sensor: Flexible potting offers full display protection and flexible installation, with a smooth surface for tight glass bonding. Soft, low-stress design protects internal electronics effectively.

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.
