Moisture-proof coating for substrates: "High reliability," "Room temperature fast drying," "Non-flammable."
FG-3650 series
Unlike UV-curable and thermosetting types, there are no uncured components left, ensuring high reliability. It dries at room temperature in 5 minutes, eliminating the need for a drying process. It is non-flammable and does not contain organic solvents, ensuring high safety.
The protective coating agent for electronic circuit boards (conformal coating) "FloroSurf FG-3650 Series" has numerous achievements in waterproofing and insulation protection for automotive circuit boards and electronic components. Additionally, it is not subject to PFAS regulations. 【Performance Features】 ■ Higher moisture and waterproofing properties compared to other resins! → It has 4 times the moisture resistance compared to urethane and acrylic-based moisture-proof coatings at the same film thickness! It exhibits more than 10 times the moisture resistance compared to silicone-based coatings. This minimizes weight increase due to the coating film, making it ideal for lightweight devices such as mobile equipment. ■ Resistant to acidic substances such as lithium battery electrolytes! → It can protect circuit boards during electrolyte leakage, preventing fire accidents. ■ It exhibits strong protective effects against acidic gases, saline solutions, and corrosive liquids, also providing rust prevention. ■ In reactive coatings (silicone, UV acrylic, etc.), unreacted components remain and affect properties. This product does not leave unreacted components (low molecular compounds), ensuring stable electrical characteristics and preventing contact failures at electrical connections after application. ■ A model with fluorescent dye for application confirmation is also available. *Please contact us if you would like a free sample.

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).
