Flywoo X30 PCBA Waterproof Spray

The Flywoo X30 PCBA Waterproof Spray applies a superhydrophobic, invisible conformal coating to protect your drone electronics from moisture and water damage. Designed for FPV builds exposed to damp conditions, snow, or water hazards, this nano-coating safeguards sensitive components like flight controllers, ESCs, and video transmitters against short circuits without the heavy thickness of traditional silicone coatings.

Key features

• Creates a superhydrophobic nano-layer to repel water and prevent electrical shorts on PCBAs.
• Leaves a thin, invisible film that maintains essential heat dissipation for high-current ESCs and VTXs.
• Pump spray application easily penetrates tight clearances under surface-mount components.
• Allows for direct soldering through the cured coating for straightforward repairs and wire swaps.

Specifications

• Water contact angle: over 160 degrees
• Surface drying time: about 2-3 minutes per coat; 2-3 coats recommended
• Coverage example: about 2.5 g for three double-sided coats on a 20 x 20 mm flight controller
• Suitable for: flight controllers, ESCs, VTXs and digital air units, board and battery plugs; lenses (reduces light transmission by about 30%, can be wiped off)

Before application, ensure your bare boards are entirely clean and dry. Always mask off barometer ports, USB connectors, and tactile boot buttons to prevent the liquid from interfering with mechanical contacts or pressure sensors.
