[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 on 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, its moisture resistance is over 3 to 10 times greater (at the same film thickness)! It exhibits 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】 ■ It can be used safely 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. No explosion-proof equipment is required, and quantity management is unnecessary. ■ Not classified as an organic solvent under occupational health and safety law → Management items such as workplace environmental measurements and organic solvent health checks for workers are no longer necessary. ■ Cures at room temperature in 5-20 minutes after application! → No special equipment like heating furnaces is required. ■ It has low viscosity, making it easy to handle. The workplace remains clean. ■ The pot life is virtually permanent. Zero waste. ■ Repairs are possible after coating.

basic information
【Performance Characteristics】 ■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. The increase in weight due to the coating film is minimized, making it ideal for lightweight devices such as mobile equipment. ■Resistant to acidic substances like electrolyte solutions in lithium batteries! → It can protect the circuit board in case 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 will not cause contact failure of electrical contacts after application. ■A model with fluorescent dye for application verification is also available. *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).
