[Case of Solvent-Free] Conformal Coating Agent Not Subject to Organic Solvents
FG-3650 series
Environmentally friendly (non-organic solvent + non-hazardous + low odor) room temperature drying moisture-proof coating agent for printed circuit boards (conformal coating agent).
The protective coating agent for electronic circuit boards (conformal coating) "FloroSurf FG-3650 series" is suitable for waterproofing and insulation protection of electronic components, as well as for moisture-proof and waterproof coatings of mounted circuit boards. It is non-flammable and does not fall under organic solvent regulations, making it free from fire safety and occupational health and safety law restrictions. Compared to urethane, acrylic, and silicone-based coatings, it offers 3 to 10 times better moisture resistance (at the same film thickness). It provides protective functions such as moisture resistance, saltwater resistance, water resistance, acid resistance, resistance to lithium battery electrolyte, and water and oil repellency, all in a thin film. 【Benefits in the Manufacturing Environment】 ■ Safe to use as it is a non-flammable, low-odor liquid. → FloroSurf FG-3650 is safe due to its non-flammability and low toxicity. It is not subject to PRTR law or fire safety regulations, eliminating the need for explosion-proof equipment and quantity management. ■ Not classified as an organic solvent under occupational health and safety law. → No need for environmental measurements in the workplace or organic solvent health checks for workers. ■ 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, and it does not dirty the workplace. ■ The pot life is virtually permanent, resulting in zero waste. ■ Repairs can be made after coating. *If you would like a free sample, please contact us.

basic information
【Performance Features】 ■Higher moisture and water resistance 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 over 10 times the moisture resistance compared to silicone-based coatings. It minimizes weight increase due to the coating film, 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 provides strong protective effects against acidic gases, saline solutions, and corrosive liquids, also exhibiting rust prevention effects. ■Since it does not contain low molecular compounds like silicone, it does not cause contact failure of electrical contacts after application. ■There are also models with fluorescent dyes for application confirmation. *We sincerely apologize, but our products are industrial chemical products and cannot be provided as samples for personal use (in cases without corporate status), medical applications, 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).
