[Case Study] Preventing metal migration due to moisture in multilayer printed circuit boards.
FG-3650 series
It has four times the moisture resistance of urethane and acrylic, and protects the substrate from humidity and moisture with a thin film. It is classified as non-hazardous under the Fire Service Act and is not subject to organic solvent regulations, ensuring high safety.
The fluorosurf FG-3650 series protective coating for electronic circuit boards has been designed and developed for waterproofing and insulation protection of electronic components, as well as for moisture-proof and waterproof coating of mounted 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. 【Reasons to Choose FG-3650】 ■ High migration prevention performance ■ Non-hazardous under the Fire Service Act, so explosion-proof equipment and quantity management are unnecessary ■ Not classified as an organic solvent (under the Industrial Safety and Health Act), making on-site management easy ■ Dries at room temperature in a short time, eliminating the need for drying equipment ■ Low odor *If you would like a free sample, please indicate "Sample Request" in your inquiry.

basic information
- 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 from the coating film, making it suitable for lightweight devices such as mobile equipment. - It is also 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 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 service law regulations. - It has low viscosity and is easy to handle. It does not make the workplace dirty. - The pot life is semi-permanent, resulting in no waste. - Repairs can be made after coating. *If you would like a free sample (limited to corporations), please include "Sample Request" in your inquiry.

Company information
Our company, Fluoro Technology Co., Ltd., is a specialized manufacturer focused on the following: * Fluorine-based water 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 agile and can respond precisely to your needs. Fluorine-based compounds are available as high-performance materials, but we specialize in room-temperature coatings that possess functions such as water and oil repellency, anti-fouling, moisture resistance, and release properties. We synthesize fluorine resin components in-house to manufacture fluorine-based coatings and water and oil repellent treatments, allowing us to customize resin properties and modify solvent specifications with great attention to detail. 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).
