Substrate coating agent strongly protects the substrate from lithium battery electrolyte.
FG-3650 series
Forms a coating resistant to lithium battery electrolyte. Numerous achievements in mobile and automotive substrates. Only requires room temperature drying, no heating needed. Non-volatile organic solvents + non-hazardous materials.
Conformal Coating (Protective Coating for Electronic Circuit Boards) "Fluorosurf 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 contain organic solvents (VOC), making it free from fire safety laws, occupational safety and health laws, and VOC regulations. Furthermore, our products do not use PFOS or PFOA at all. 【Performance Features】 ■ High resistance to acidic substances such as the electrolyte of lithium batteries → Protects the circuit board in case of electrolyte leakage, preventing fire accidents. ■ Higher moisture-proof and waterproof properties compared to other resins → Provides four times the moisture-proof performance compared to urethane or acrylic moisture-proof coatings at the same film thickness! Exhibits more than ten times the moisture-proof performance 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. ■ 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 for application confirmation is also available. *Please contact us if you would like a free sample.

basic information
**Benefits in the Manufacturing Field** ■ Safe to use as it is a non-flammable, low-odor liquid! → FluoroSurf FG-3650 is non-flammable and low in toxicity, making it safe. 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 the Industrial Safety and Health Act → Management items such as workplace environmental measurements and organic solvent health checks for workers are not required. ■ Not classified as VOC → It also complies with VOC regulations. ■ 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. The workplace remains clean. ■ Pot life is semi-permanent. Zero waste. ■ Repairs are possible after coating. *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 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).
