TECHOEL FS8907

    TECHOEL FS8907 Nano Waterproof Agent

     

    Description

    The TECHOEL FS8907 series of electronic water-repellent coatings is a fluorinated compound solution with water and oil repellency, using a fluorinated solvent as the medium. When applied to metal and plastic surfaces, it forms a very thin film on the coated surface after drying. Due to the low surface tension of this film, it can prevent the penetration, outflow, and adhesion of lubricating oil, silicone oil, liquid resin, water, etc.

    This protective film is usually only a thin layer (about 0.5-2.5μm), which can enhance the moisture, stain, dust, and chemical resistance of electronic products. It prevents issues such as continued corrosion of solder joints and conductors in contact with air, provides shielding, eliminates certain electromagnetic interferences, and offers insulation.

    Product Applications

    • 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.

    Performance Principles

    • The wettability of a liquid on a solid is determined by their respective surface tensions when the liquid contacts the solid.
    • The surface tension of a solid is represented by its critical surface tension (γC). When the relationship with the liquid surface tension is 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.

    High-Performance Fluorinated Resin Film

    • On plastic, metal, and glass surfaces, a thin, transparent, and highly flexible film of about 1μm is formed at room temperature. With extremely low surface tension (11~12mN/m), it is easy to apply and offers excellent water, oil, and stain resistance.
