Substrate protection coating: Performance, safety, and environmental considerations prioritized in design; non-hazardous materials.
Conformal Coating Agent FluoroSurf FG-3650 Series
Since it is not a hazardous material, explosion-proof equipment is not required / hazardous material storage is not needed. Organic solvents are not applicable, reducing management items. It has low odor and can be dried at room temperature only, so drying equipment is not necessary.
The "FloroSurf FG-3650 Series" conformal coating agent for electronic circuit boards is designed with a high moisture resistance of 4 to 10 times that of other resins, prioritizing safety and environmental preservation. It does not use regulated substances such as those under the Fire Service Act, Industrial Safety and Health Act, or PFAS regulations, and it has low odor, ensuring a safe and pleasant workplace environment. This coating agent is ideal for waterproofing and insulating protection of electronic components, as well as moisture and waterproofing of mounted circuit boards. 【Features】 ■ Non-flammable and low-odor liquid for safe use. → FloroSurf FG-3650 is non-flammable and low in toxicity, exempt from PRTR and Fire Service Act regulations. It is also not classified as an organic solvent under the Industrial Safety and Health Act. ■ Higher moisture and waterproofing performance compared to other resins! → It has four times the moisture resistance of urethane and acrylic systems, and ten times that of silicone systems. Its thin film allows for weight reduction, making it suitable for mobile circuit boards, automotive circuit boards, and aircraft circuit boards. ■ Resistant to acidic substances such as lithium battery electrolytes! → It can protect circuit boards during electrolyte leakage, preventing fire accidents. *If you would like a free sample and technical booklet, please include "Sample Request" or "Booklet Request" in your inquiry.

basic information
【Other Features】 ■ Since it does not contain unreacted low molecular compounds like silicone (moisture-curing type) or UV-curing type, it will not cause contact failure of electrical contacts or film peeling due to leaching of unreacted components after application. ■ It dries at room temperature, with a drying time of 5 seconds to 30 minutes. No heating required. No drying equipment needed. ■ It has low viscosity and is easy to handle. The workplace remains clean. ■ There is no pot life, so there is no waste. ■ Repairs are possible after coating. ■ The model with fluorescent dye allows for verification of the application area under black light. (Optional) *We sincerely apologize, but as our products are industrial chemical products, we cannot provide samples for personal use (in cases without corporate status), medical use, or applications that come into 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).
