Substrate coating agent "waterproof, insulation, migration prevention, acid resistance"
For waterproofing and insulation of electronic components, and moisture-proof and waterproof coating of mounting boards! Four times the moisture-proof performance of urethane and acrylic systems! Non-flammable and highly safe! *Samples available.
The fluorosurf FG-3650 series protective coating for electronic circuit boards is suitable 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. Free samples are available upon request. 【Features】 ■ Four times the moisture resistance compared to urethane and acrylic-based moisture-proof coatings. ■ Being a thin film, it minimizes weight increase, making it suitable for lightweight devices such as mobile equipment. ■ Provides strong protection against acidic gases, saline solutions, and corrosive liquids, also offering rust prevention. ■ Non-flammable and low-odor, ensuring safe usage without fire safety regulations. ■ Dries at room temperature, with a drying time of 5 seconds to 30 minutes. No heating is required. *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 due to 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 dirty the workplace. - The pot life is semi-permanent, eliminating waste. - Repairs are possible after coating. *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.
