[Conformal Coating Example] Preventing leaks and corrosion of electronic substrates due to condensation.
High insulation and high water-repellent conformal coating. The fluorine film protects the printed circuit board from moisture and humidity. Non-flammable and highly safe. Free of regulated substances.
The conformal coating agent, Fluorosurf FG-3650 series, is specially designed for waterproofing and insulation protection of electronic components, as well as moisture and waterproofing of mounted circuit boards. It has four times the moisture resistance compared to urethane and acrylic-based coatings, and exhibits protective functions such as insulation, moisture resistance, saltwater resistance, water resistance, acid resistance, resistance to lithium battery electrolyte, and water and oil repellency, all in a thin film. It can be applied using a dispenser or spray, and the application is completed in just 5-10 minutes with room temperature drying! It is non-flammable and not subject to fire safety laws, nor does it fall under the organic solvent regulations of the Industrial Safety and Health Act, significantly reducing on-site management items and equipment costs. Fluorine-based regulated substances (such as PFOS, PFOA, PFHxS) are not used. *We offer free samples to those who request them (limited to corporations). If you would like a free sample, please include "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. - Since it does not contain low molecular compounds like silicone, 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 model with fluorescent dye (optional) allows for easy application confirmation under black light. - 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, keeping the workplace clean. - The pot life is semi-permanent, resulting in no waste. *We sincerely apologize, but our products are industrial chemical products, and we cannot provide samples for personal use (in cases without corporate status), medical use, or applications involving contact with food.
