Moisture-proof coating agent, dries at room temperature in 3 minutes, non-flammable, free of regulated substances.
FG-3650 series
Numerous achievements in vehicle-mounted circuit boards. Environmentally friendly (non-organic solvent + non-hazardous + low odor) moisture-proof coating agent for printed circuit boards. Dries at room temperature without the need for heating.
The protective coating agent for electronic circuit boards (conformal coating) "Fluorosurf FG-3650 series" exhibits protective functions such as moisture resistance, gasoline resistance, saltwater resistance, water resistance, acid resistance, resistance to lithium battery electrolyte, and water and oil repellency with a thin film coating. It has numerous achievements in waterproofing and insulation protection of electronic components, as well as moisture and waterproof coatings for mounted circuit boards. It is non-flammable and does not fall under organic solvent regulations, making it free from fire safety and occupational safety regulations. Additionally, it does not contain any PFOS, PFOA, or PFHxS. 【Performance Features】 ■ High moisture and water resistance → Compared to urethane and acrylic-based moisture-proof coatings of the same film thickness, it has four times the moisture-proof performance! It exhibits more than ten times the moisture resistance compared to silicone-based coatings. The increase in weight due to the coating film is minimized, making it ideal for lightweight devices such as mobile equipment. ■ High resistance to acidic substances such as lithium battery electrolytes → It can protect the circuit board in the event of electrolyte leakage, preventing fire accidents. ■ It exhibits strong protective effects against acidic gases, saline solutions, and corrosive liquids, also providing rust prevention effects. ■ Since it does not contain low molecular compounds, it will not cause contact failure of electrical contacts after application. *If you would like a free sample, please contact us.

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).
