Waterproof And Moisture-proof Nano-coating
Waterproof nano-coating is a colorless, transparent, non-flammable liquid that forms an ultra-thin moisture-, salt- and corrosion-resistant insulating film on PCBs and electronic components. Applied by dipping or spraying, it protects smartphones, FPCs, earphones, audio devices and LED lighting.
Product Overview
Waterproof and moisture-proof nano-coating is a colorless, transparent, ultra-thin, quick-drying liquid nanomaterial that is non-toxic, non-flammable and low in odor, and it provides moisture-proof, salt-resistant and corrosion-resistant protection. It is applied by dipping, spraying or brushing and, after room-temperature drying or rapid baking, forms a nanometer-thick waterproof, insulating, salt-resistant film on PCBs and electronic components. With a 2 μm film, 60 s finger-drying time and volume resistivity of 5.73×10 21 Ω·cm, it protects smartphones, flexible circuit boards, earphones, audio devices, sports cameras and LED lighting.

Key Benefits
- Non-toxic, non-flammable and low odor
- Ultra-thin transparent film that leaves components visible
- Fast curing at room temperature for efficient production
- High volume resistivity and dielectric strength
- Reworkable, VOC-free and RoHS compliant
Applications
- Smartphones — moisture and corrosion protection for main boards
- Tablets — flexible printed circuit boards (FPC)
- Wearables and audio — Bluetooth sports earphones, audio devices and sports cameras

Usage & Handling
Clean products before coating and tighten the cap promptly after opening. For mobile phones use selective coating and mask connectors, acoustic parts and appearance parts; large circuit boards should be low-pressure sprayed. The coating is reworkable and can be removed with a soft plastic sheet or by ultrasonic immersion in a fluorinated solvent. Packaging: 1kg bottles, or 5kg or 30kg drums.
