Electronic circuit board protective coating agent [Migration prevention] Non-hazardous material
High-performance fluorine-based coating agent, free of regulated substances.
The fluorosurf FG-3650 series protective coating for electronic substrates is suitable for waterproofing and insulation protection of electronic components, as well as moisture-proof and waterproof coating for 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 with a thin film. Free samples are available upon request. 【Introduction to Background】 ■ Prevent metal migration due to moisture in multilayer mounted circuit boards ■ Short circuits and failures caused by water droplets and humidity during outdoor use ■ Prevention of fire due to short circuits from leakage of lithium battery electrolyte ■ Occurrence of leaks and malfunctions due to condensation in high humidity *If you would like a free sample, please include "Request for Sample" in your inquiry.
basic information
- Does not use regulated substances such as PFOA, PFOS, and PFHxS. - 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. - Resistant to the electrolyte of lithium batteries. It can protect the substrate in case of electrolyte leakage, preventing fire accidents. - Exhibits strong protective effects against acidic gases, saline solutions, and corrosive liquids, also providing rust prevention. - Does not contain low molecular compounds like silicone, so it will not cause contact failure of electrical contacts after application. - Dries at room temperature, with a drying time of 5 seconds to 30 minutes. No heating required. - The non-flammable solvent type is non-flammable and low toxicity. It is not subject to PRTR law or fire service law regulations. - Low viscosity makes it easy to handle. The workplace remains clean. - The pot life is semi-permanent, resulting in no waste. - Repairs are possible after coating. *We sincerely apologize, but our products are industrial chemical products and cannot be provided as samples for personal use (in cases without corporate status), medical use, or applications that come into contact with food.
