Fluorine coating agent case study: Strongly protects printed circuit boards from moisture and acids.
FG-3650 series
Fluorine coating is ideal for substrate coating. It has four times the moisture and water resistance of urethane and acrylic coatings when dried at room temperature. It is non-flammable and safe.
The fluorine coating agent (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 printed circuit boards. 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. PFAS-regulated substances are not used. 【Features】 ■ Non-flammable and low-odor liquid, making it safe to use! Not classified as an organic solvent. → FloroSurf FG-3650 is safe due to its non-flammability and low toxicity. It is not subject to PRTR law or fire service law 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. → This reduces management items such as environmental measurements and organic solvent health checks for workers. ■ Higher moisture and waterproofing performance compared to other resins! → It has four times the moisture-proof performance compared to urethane and acrylic-based moisture-proof coatings. ■ Resistant to acidic substances such as lithium battery electrolytes! → It can protect the circuit board during electrolyte leakage, preventing fire accidents. ■ Cures at room temperature in 5-20 minutes after application! → No special equipment like heating furnaces is required. ☆ Currently providing samples and a moisture-proof coating handbook exclusively for corporate clients.

basic information
【Other Features】 (PFAS-free) ■ It has four times the moisture-proof performance compared to urethane and acrylic-based moisture-proof coatings, providing moisture protection with a thin film. It minimizes weight increase due to the coating film, making it ideal for lightweight devices such as mobile equipment. ■ It is resistant to the electrolyte of lithium batteries. It can protect the substrate in case of electrolyte leakage, preventing fire accidents. ■ It exhibits strong protective effects against acidic gases, saline solutions, and corrosive liquids, also providing rust prevention. ■ Unlike silicone, it does not contain low molecular compounds, so it will not cause contact failure of electrical contacts after application. ■ It dries at room temperature, with a drying time of 5 to 30 minutes. No heating is required. ■ The non-flammable solvent type is non-flammable and low in toxicity. It is not subject to PRTR law or fire safety regulations. ■ It has low viscosity and is easy to handle, keeping the workplace clean. ■ The pot life is semi-permanent, resulting in no waste. ■ Repairs can be made after coating. ■ There are models with fluorescent dyes for application confirmation. *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 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).
