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 & Shipping & Storage

1. Hardener: Typically 5KG/10KG/25KG/200KG metal or plastic drums.
2. Resin: Typically 25KG/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.
