Conformal coating agent, environmentally friendly, room temperature drying, SDGs.
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 substrates (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 substrates. 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 more than 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】 Perfectly aligned with SDGs ■ Non-flammable and low-odor liquid, making it safe to use → Safe due to its non-flammability and low toxicity. 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 → Eliminates the need for environmental measurements in the workplace and organic solvent health checks for workers. ■ Cures at room temperature in just 5-20 minutes after application! → No special equipment or processes, such as heating furnaces, are required. ■ Low viscosity makes it easy to handle. The workplace remains clean. ■ Pot life is virtually indefinite. Zero waste. ■ Repairs are possible after coating. *If you would like a free sample, please contact us.

basic information
【Performance Features】= High performance with proven results in automotive circuit boards and various other fields. ■ Higher moisture and water resistance compared to other resins! → It offers four times the moisture resistance compared to urethane and acrylic-based moisture-proof coatings at the same film thickness! 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. ■ Resistant to acidic substances such as lithium battery electrolytes! → 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 does not cause contact failure of electrical contacts after application. ■ A model with fluorescent dye is also available for coating verification. *We sincerely apologize, but our products are industrial chemical products, and we cannot provide 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).
