TECHOEL FA8007 nano waterproof coating
Product Description
TECHOEL FA8007 nano waterproof agent is a fluorinated compound solution that utilizes a fluorinated solvent as its medium, possessing water and oil repellency properties.
When applied to metal and plastic surfaces, it forms a very thin film on the coated surface after drying. This film exhibits very low surface tension, effectively preventing the penetration, outflow, and adhesion of lubricating oil, silicone oil, liquid resin, water, etc. This protective film, typically just a thin layer, enhances the moisture, stain, dust, and chemical resistance of electronic products.
It prevents issues such as continued corrosion of solder joints and conductors exposed to air, provides shielding against and elimination of certain electromagnetic interferences, and offers insulation.

Performance Principles
- The wettability of a liquid on a solid is determined by their respective surface tensions when the liquid comes into contact with the solid;
- The surface tension of a solid is represented by its critical surface tension (γc). When the liquid surface tension satisfies γ ≦ γc, the liquid will wet (spread on) the solid surface;
- If a dry film with lower surface tension (γ) than the liquid is formed on the solid surface, the liquid will flow or remain stationary on the interface without wetting.
Product Applications
- Extends lifespan, provides moisture and water resistance, and improves dielectric properties;
- Protective coating for circuit boards and electronic components;
- Prevents the diffusion of lubricating oil in precision instruments (such as watches, cameras, etc.) or micro-motor bearings;
- Sealing treatment for precision components. Water and oil repellent coating for circuit boards in mobile communication devices such as mobile phones;
- Prevents erosion by acidic liquids;
- Forms a protective coating resistant to chemicals such as saltwater, electrolytes, and corrosive gases.
