[Case of Solvent-Free] Low-Odor Fluorine-Based 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 "FloroSurf FG-3650 Series" protective coating agent for electronic circuit boards (conformal coating) 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 the category of organic solvents, making it free from regulations under the Fire Service Act and the Industrial Safety and Health Act. Compared to urethane-based, acrylic-based, and silicone-based coatings, its moisture resistance is 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 Manufacturing Environments】 ■ 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 Service Act regulations. No need for explosion-proof equipment or quantity management. ■ 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 no longer necessary. ■ Cures at room temperature in 5-20 minutes after application → No special equipment like heating furnaces is required. ■ Low viscosity makes it easy to handle. The workplace remains clean. ■ Pot life is virtually permanent. Zero waste. ■ Repairs are possible after coating. *If you would like a free sample, please contact us.

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 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 equipment. ■Resistant to acidic substances such as lithium battery electrolytes! → It can protect the substrate in the event of electrolyte leakage, preventing fire accidents. ■Exhibits strong protective effects against acidic gases, saline solutions, and corrosive liquids, also providing rust prevention effects. ■Does not contain low molecular compounds like silicone, so it will not cause contact failure of electrical contacts after application. ■A model with fluorescent dye is also available for application verification. *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 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).
