[Fluorine Coating Agent Example] Protects printed circuit boards from battery electrolyte.
FloroSurf FG-3650 Series / FS-1610 Series
A fluororesin coating with acid resistance prevents ignition of the substrate in the event of electrolyte leakage. It is a room-temperature drying fluorine coating agent that also prevents corrosion of metal parts.
Fluorine coating agents exhibit outstanding resistance to lithium battery electrolyte compared to other resin coating agents. They can prevent fires caused by circuit short-circuits when the electrolyte leaks, as well as corrosion of metal parts. They provide protective functions such as moisture resistance, saltwater resistance, water resistance, acid resistance, resistance to lithium battery electrolyte, and water and oil repellency in a thin film. They have a proven track record of being adopted as safety measures in various fields, including aircraft, automotive circuit boards, and mobile devices. **Challenges Addressed by Fluorine Coating** - No short-circuit occurs even if lithium battery electrolyte leaks and adheres to the pattern part of the circuit board. - Can be easily applied with dispensers and dries within a few minutes at room temperature. No drying process is required. - Non-hazardous materials with no fire safety regulations. No quantity management or explosion-proof measures are necessary. - Not classified as organic solvents under the Industrial Safety and Health Act. Regular organic health checks are not required. *We offer free samples to those who request them (limited to corporate clients).

basic information
■ Fluorine coating has excellent resistance to the electrolyte of lithium batteries. It can protect the substrate in the event of electrolyte leakage and prevent fire accidents caused by short circuits. ■ It has four times the moisture-proof performance compared to urethane and acrylic-based moisture-proof coatings, providing moisture protection effects with a thin film. It minimizes weight increase due to the coating film, making it suitable for lightweight devices such as mobile equipment. ■ It exhibits strong protective effects against acidic gases, saline solutions, and corrosive liquids, also providing rust prevention effects. ■ Unlike silicone, it does not contain low molecular compounds, so it does not cause contact failures in electrical connections after application. ■ It dries at room temperature, with drying times ranging from 5 seconds to 30 minutes. No heating is required. ■ The non-flammable solvent type is non-flammable and low toxicity. It is not subject to PRTR law or fire safety regulations, eliminating the need for explosion-proof equipment or quantity management. ■ It does not fall under the organic solvents regulated by the Industrial Safety and Health Act. ■ It has low viscosity and is easy to handle. It does not dirty the workplace. ■ The pot life is semi-permanent, resulting in no waste. ■ Repairs can be made after coating. ■ There is also a model with fluorescent dye for application confirmation under black light.

Company information
Our company, Fluoro Technology Co., Ltd., is a specialized manufacturer focusing on the following: * Fluorine-based water-repellent and oil-repellent coatings * Non-flammable conformal coatings (moisture-proof coatings for substrates) * Dry release agents, aerosol-type fluorine release agents * Anti-fouling (fingerprint prevention) coatings We are flexible and responsive to your company's needs. While there are many fluorine-based compounds available as high-performance materials, we specialize in room-temperature coatings that possess functions such as water-repellent, oil-repellent, anti-fouling, moisture-proofing, and release properties. Our company synthesizes fluorine resin components in-house, allowing us to manufacture fluorine-based coatings and water-repellent and oil-repellent treatments. This enables us to provide detailed customization of resin properties and changes in solvent specifications. Additionally, we have accumulated a wealth of technical information regarding usage methods and applications, which we can provide for various purposes. Please note that our products do not contain regulated substances (PFOS, PFOA, PFHxS, and long-chain PFCA with C8 or higher).
