Product Description

Silicone Potting Compound INI-9325

Two-component silicone, platinum-curing, flowable, vulcanizes at room temperature.

Can be used for a long time in the temperature range of - 65 ° C - 200 ° C and keep its soft and elastic properties.

Application:

Used for potting, encapsulating, sealing and bonding, widely used in electronic products, electricity, power supply, automotive etc. For example, used for potting of electronic components, power module and control module and controllers, junction box, solar cell assembly etc.

Can reduce stress and withstand high and low temperature impact. For the high power control module, thermal conductive silicone is used to achieve the function of heat dissipation, or outdoor protection for electronics such as LED screen. Improve the insulation level of electronics, improve heat dissipation, and avoid the risk of electronics overheating and burning in a short time.

Features & Advantages

  • High transparency and low viscosity
  • Food grade, FDA certificate
  • Excellent anti-corrosion and weather aging resistance
  • Superior insulation and fire proof (UL94-V0)
  • Waterproof, moisture proof, and anti-fouling
  • Quake-proof and thermal conductive
  • Low shrinkage and ozone resistance
  • Operable in harsh environments (salt fog, vibration, deep sea, etc.)

Operation Instructions

1. Mixing: Mix part A and part B evenly with the specified mixing ratio. Weigh exactly using electronic scales.

2. Vacuum Pumping: (Optional but recommended) To ensure no bubbles in the finished mold. This step should be under 10 minutes.

3. Pouring or Brushing: Use pouring for simple patterns (low viscosity required) or brushing for delicate patterns (high viscosity required).
