Technical Parameters

Product Applications

1. LED Flexible Strip Light: High flexibility for bendable installation, strong adhesion, reliable LED/FPC protection, and food-grade environmental compliance.
2. LED Outdoor Lighting: 5-year anti-yellowing, excellent thermal shock resistance across temperatures, IP68-rated waterproof, suitable for prolonged outdoor exposure.

Directions for Use

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.

Packing

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