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.

    

    

   9. This series of products are room-temperature-curing, addition-cure two-component silicone. During the dispensing process, avoid contact with the following three types of materials to prevent reactions that may affect the curing effect:

       a. Organotin compounds and organotin-containing silicone rubber.

       b. Sulfur, sulfides, and sulfur-containing materials.

       c. Amine compounds and amine-containing materials.

    

     10. It should be noted that during manual operation, when vacuumizing the mixed A+B adhesive, the vacuum pressure must be controlled to ensure the adhesive is not completely sucked out of the container by the vacuum.

Packing & Shipping & Storage

1. Part A: Typically supplied in 25kg sealed plastic drums.
2. Part B: Typically supplied in 25kg sealed plastic drums.
3. Store and transport as a general chemical product.
