KEY-221 Hejing · Electronic Nanocoating

Product Highlights

Product Description

KEY-221 Hejing electronic nanocoating is a colorless, transparent, and low-odor liquid with ultra-low viscosity and ultra-high leveling properties. After simple impregnation, spraying, or other processes, and followed by room temperature drying or rapid baking, it can form a waterproof, moisture-proof, insulating, and corrosion-resistant coating on electronic PCBA circuit boards, various components, and ITO surfaces.

This coating is completely colorless and transparent, does not affect electronic signals or heat dissipation, is non-flammable and non-explosive, safe and environmentally friendly, and has wide applications in industries such as smart wearables, smart healthcare, smart homes, military communications, and new energy.

Features

• High Hydrophobicity: Low surface energy (<10 dyne), capable of covering narrow gaps.
• Ultra-thin: Coating thickness as low as 2-3μm, colorless and transparent.
• Excellent Weatherability: Resistant to UV radiation, extreme temperature fluctuations, waterproof, rustproof, and corrosion-resistant (salt spray resistance, oxidation resistance, acid and alkali resistance).?
• High Insulation: High impedance value, high density, minimal porosity.
• No Impact on Signals or Heat Dissipation: Thin coating thickness with excellent thermal conductivity.
• Superior Adhesion: Suitable for diverse substrates including metals, glass, ceramics, polymers, composites, and laminates.
• Simple Process: Quick-drying formulation compatible with dip coating, spot coating, flow coating, spray coating, and other application methods.
• Repairable: Supports direct solder repair; coating is easily removable and can be recoated for rework.
• Environmentally Friendly & Non-Toxic: Utilizes eco-friendly electronic fluorinated liquid with minimal odor, posing no harm to humans and being environmentally compatible.
