Product Applications

  1. Column membranes: Strong adhesion to ABS casings, with superior corrosion and water resistance, ensuring durable bonding and long-term stability for membrane materials and filaments.
  2. Water purification filter elements: High bonding strength, eco-friendly formulation, and NSF-certified compliance.


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

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

Resin: 10KG / 20KG / 200KG metal or plastic drums.
