Electronic circuit board protective coating agent [Migration prevention] Non-hazardous material
FG-3650 series
High-performance fluorine-based coating agent, free of regulated substances.
The fluorosurf FG-3650 series protective coating for electronic circuit boards is suitable for waterproofing and insulation protection of electronic components, as well as for moisture-proof and waterproof coating of mounted circuit boards. It exhibits protective functions such as moisture resistance, saltwater resistance, water resistance, acid resistance, resistance to lithium battery electrolyte, and water and oil repellency with a thin film. Free samples are available upon request. 【Introduction to Background】 ■ Prevent metal migration due to moisture in multilayer mounted circuit boards. ■ Short circuits and failures caused by water droplets and humidity during outdoor use. ■ Prevention of fire due to short circuits from lithium battery electrolyte leakage. ■ Occurrence of malfunctions and corrosion due to leaks caused by condensation in high humidity. *If you would like a free sample, please include "Request for Sample" in your inquiry.

basic information
- Does not use regulated substances such as PFOA, PFOS, and PFHxS. - Offers four times the moisture resistance 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. - Resistant to the electrolyte of lithium batteries. It can protect the substrate in case of electrolyte leakage, preventing fire accidents. - Exhibits strong protective effects against acidic gases, saline solutions, and corrosive liquids, also providing rust prevention. - Does not contain low molecular compounds like silicone, so it will not cause poor contact at electrical connections after application. - Dries at room temperature, with a drying time of 5 seconds to 30 minutes. No heating required. - The non-flammable solvent type is non-flammable and low toxicity. It is not subject to PRTR law or fire service law regulations. - Low viscosity makes it easy to handle. The workplace remains clean. - The pot life is semi-permanent, eliminating waste. - Repair is possible after coating. *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 focused on the following: * Fluorine-based water 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 agile and can respond precisely to your needs. Fluorine-based compounds are available as high-performance materials, but we specialize in room-temperature coatings that possess functions such as water and oil repellency, anti-fouling, moisture resistance, and release properties. We synthesize fluorine resin components in-house to manufacture fluorine-based coatings and water and oil repellent treatments, allowing us to customize resin properties and modify solvent specifications with great attention to detail. 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).
