Coating agent for drone circuit boards: lightweight and provides strong protection against moisture for the circuit board.
FG-3650 Series
A protective coating agent that is lighter than other resin coatings and protects substrates from water and acids, with many proven applications in mobile and automotive substrates.
Conformal Coating (Protective Coating for Electronic Circuit Boards) "FloroSurf FG-3650 Series" is suitable for waterproofing and insulation protection of electronic components, as well as for moisture and waterproof coating of mounted circuit boards. It is non-flammable and does not contain any regulated substances such as those under the Fire Service Act, Industrial Safety and Health Act, VOC regulations, or PFAS regulations, as it is free from organic solvents (VOC). 【Performance Features】 - Compared to other resin coatings, it offers high moisture and waterproof properties, contributing to weight reduction. → It provides four times the moisture resistance of urethane or acrylic-based moisture-proof coatings at the same film thickness! It exhibits more than ten times the moisture resistance compared to silicone-based coatings. - High resistance to acidic substances such as lithium battery electrolytes. → It can protect the circuit board in case of electrolyte leakage, preventing fire accidents. The increase in weight due to the coating film is minimized, making it ideal for lightweight devices such as mobile equipment. - It demonstrates strong protective effects against acidic gases, saline solutions, and corrosive liquids, also providing rust prevention. - It 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 verification is also available. *If you would like a free sample, please contact us.

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).
