Moisture-proof, waterproof, and acid-resistant coating for substrates - FluoroSurf FG-3650
FG-3650 series
Proven performance for large aircraft printed circuit boards! Four times the moisture resistance of urethane and acrylic coatings! Strongly protects circuit boards.
The "FloroSurf FG-3650 Series" electronic substrate protective coating agent (conformal coating agent) is suitable for waterproofing and insulating protection of electronic components, as well as for moisture-proof and waterproof coating of mounted substrates. It exhibits protective functions such as moisture resistance, saltwater resistance, water resistance, acid resistance, resistance to lithium battery electrolyte, water and oil repellency, gasoline resistance, migration prevention, and condensation leak prevention, all in a thin film. 【Features】 ■ It is a non-flammable, low-odor liquid, making it safe to use! → FloroSurf FG-3650 is non-flammable and low in toxicity, thus not subject to PRTR law or fire service law regulations. It is also not classified as an organic solvent under the Industrial Safety and Health Act. ■ It has higher moisture and waterproof properties compared to other resins! → It has four times the moisture resistance performance compared to urethane and acrylic-based moisture-proof coatings. ■ It is resistant to acidic substances such as lithium battery electrolytes! → It can protect the substrate 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】 - The thin film provides moisture protection, minimizing weight increase from the coating, making it suitable for lightweight devices such as mobile equipment. - It is resistant to the electrolyte of lithium batteries, protecting the substrate in case of electrolyte leakage and 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 seconds 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. - It contains fluorescent dye, allowing 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 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).
