Application Instructions

• Preparation:

  • Ensure the workpiece surface is dry, clean, dust-free, and oil-free.
  • Prepare a clean and dry container for immersion (plastic or glass materials are recommended).

• Filling the Container:

  • Pour an appropriate amount of liquid into the container. Ensure the liquid depth is sufficient to submerge the highest point of the PCB by at least 5mm.

• Immersion:

  • Immerse the PCB in the liquid for 1-4 seconds, depending on the specific component requirements.
  • Remove the board and allow it to air dry for approximately 2 minutes.

• Curing:

  • Room Temperature:
    • Surface dry in 2-10 minutes, fully cured in 12-24 hours.
    • For batch production, assembly steps can begin after the surface dries.
  • Heat Curing:
    • Recommended temperature range is 60-100°C, adjusted to the lowest heat tolerance of components.
    • For example, if lithium batteries are present on the board, bake at 60°C for 30 minutes.

• Coverage:

  • Application area is approximately 5-20 square meters per kilogram.

Precautions

• Masking:

  • Before application, mask PCBA connector areas, soft ribbon cable interfaces, and button gaps. The nano coating’s insulating properties can affect these components, leading to reduced conductivity or malfunctions.

• Immersion Time:

  • Keep immersion time to 1-2 seconds. Prolonged immersion can result in excessive coating accumulation, potentially increasing the thickness beyond the nano-scale to the micro-scale. This may impair sensitive components, such as reducing microphone sound quality.

• Handling the Container:

  • If the container is temporarily idle, cover it to minimize evaporation and exposure to ambient moisture, which can cause side reactions and affect liquid performance.

• Dilution and Storage:

  • Monitor liquid concentration during use. Evaporation may lead to increased concentration, requiring dilution before reuse.
  • For extended non-use periods, transfer the liquid back to a dedicated sealed storage bottle.

Storage

• Recommended Storage Temperature: 18-25℃
• Shelf Life: 24 months.

Packaging

• 1 kg per container
• 4.3 kg per container
