PCB printed circuit board coating agent "high moisture resistance, waterproofing, high reliability"
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. Cures at room temperature without the need for heating.
The protective coating agent for electronic circuit boards (conformal coating) "FloroSurf 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 is ideal for waterproofing and insulation protection of electronic components, as well as moisture-proof 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, and contains no PFOS or PFOA. 【Performance Features】 ■ High moisture and water resistance → Compared to urethane and acrylic-based moisture-proof coatings of the same film thickness, it has 4 times the moisture resistance! It exhibits more than 10 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 devices. ■ 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 like silicone, it will not cause contact failure of electrical contacts after application. *If you would like a free sample, please contact us.

basic information
**Benefits in the Manufacturing Field** ■ Non-flammable and low-odor liquid, making it safe to use! → Fluorosurf FG-3650 is non-flammable and low-toxicity, ensuring safety. It is not subject to PRTR law or fire safety regulations. No explosion-proof equipment is required, and quantity management is unnecessary. ■ Not classified as an organic solvent under the Industrial Safety and Health Act → Management items such as workplace environmental measurements and organic solvent health checks for workers are not required. ■ Cures at room temperature in 5-20 minutes after application! → No special equipment like heating furnaces is necessary. ■ Low viscosity makes it easy to handle. The workplace remains clean. ■ Pot life is semi-permanent. Zero waste. ■ Repairs are possible after coating. ■ A model with fluorescent dye is also available for application verification. *We sincerely apologize, but as our products are industrial chemical products, 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).
