Conformal Coating Case Study: Prevention of Leakage in Electronic Circuit Boards Due to Condensation
FG-3650 Series
High insulation and high water-repellent conformal coating. The fluorine film protects the printed circuit board from moisture and humidity. Non-flammable and highly safe. Free from regulated substances.
The conformal coating agent FluoroSurf FG-3650 series is a specially designed coating agent for waterproofing and insulation protection of electronic components, as well as for moisture and waterproofing of mounted circuit boards. It has four times the moisture resistance compared to urethane and acrylic-based coatings, and it exhibits protective functions such as insulation, moisture resistance, saltwater resistance, water resistance, acid resistance, resistance to lithium battery electrolyte, and water and oil repellency, all in a thin film. It can be applied using a dispenser or spray, and the application is completed in 5-10 minutes with room temperature drying! It is non-flammable and not subject to fire safety laws, nor is it classified as an organic solvent under occupational safety and health laws, significantly reducing management items and equipment costs on-site. Fluorinated regulated substances (such as PFOS, PFOA, PFHxS, etc.) are not used. *Free samples are available upon request (limited to corporations). If you would like a free sample, please include "Sample Request" in your inquiry.

basic information
- It has four times the moisture-proof performance compared to urethane and acrylic-based moisture-proof coatings, providing moisture protection with a thin film. It minimizes weight increase from the coating film, making it suitable for lightweight devices such as mobile equipment. - It is also resistant to the electrolyte of lithium batteries. It can protect the substrate in case of electrolyte leakage, preventing fire accidents. - It exhibits strong protective effects against acidic gases, saltwater, and corrosive liquids, also providing rust prevention. - Unlike silicone, it does not contain low molecular compounds, so it will not cause contact failure of electrical contacts after application. - It dries at room temperature, with a drying time of 5 seconds to 30 minutes. No heating is required. - The model with fluorescent dye (optional) allows for easy application confirmation under black light. - The non-flammable solvent type is non-flammable and low in toxicity. It is not subject to PRTR law or fire service law regulations. - It has low viscosity and is easy to handle, keeping the workplace clean. - The pot life is semi-permanent, resulting in no waste. *We sincerely apologize, but our products are industrial chemical products, and we cannot provide samples for personal use (in cases without corporate status), medical use, or applications involving contact with food.

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).
