Product Applications


  1. Automotive Electronics: Excellent Electrical Performance, Vibration Resistance, Flame Retardant V0 Class, Heat Stability and Reliability
  2. Low-altitude aircraft: Low density can be combined with lightweight design, flexible materials, and waterproof IP68
  3. Sensor: low density, flame-retardant V0, low dielectric constant, and low-temperature resistant;
  4. Industrial controllers and control boards: Excellent high-temperature resistance, compliant with RTI 130 temperature rating standards, featuring high thermal conductivity and heat dissipation capabilities, with V0-class fire resistance.
  5. Other electronic products: Flame-retardant V0, UL Yellow Card, compliant with RTI 130 temperature resistance standard. Their outstanding electrical and mechanical properties meet most electronic products' requirements for high-performance materials.



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/25KG/200KG metal or plastic drums.
  2. Resin: Typically 25KG/200KG metal or plastic drums.
