Hydrogen sulfide countermeasure coating agent, volcanic gas countermeasure, high acid resistance to prevent corrosion.
FG-5040 series FG-3650 series
Acid-resistant fluorine coating protects printed circuit boards and metals from hydrogen sulfide. Only air-dried at room temperature. Non-flammable and highly safe.
The acid-resistant coating agent FG-5040 and the protective coating agent for electronic substrates, the Fluorosurf FG-3650 series, are coatings designed for acid resistance and anti-conversion. They have four times the moisture resistance compared to urethane and acrylic-based coatings, and they exhibit protective functions such as resistance to hydrogen sulfide, acid resistance, corrosion resistance, insulation, moisture resistance, saltwater resistance, water resistance, acid resistance, resistance to lithium battery electrolyte, and water and oil repellency, all in a thin film. They can be applied using a dispenser or spray, and the application is completed in 5-10 minutes with room temperature drying! They are non-flammable and not subject to fire safety laws, nor are they classified as organic solvents under the Industrial Safety and Health Act, significantly reducing management items and equipment costs on-site. *Free samples are available for those who wish (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 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 the event of electrolyte leakage, preventing fire accidents. - It exhibits strong protective effects against acidic gases, hydrogen sulfide gas (volcanic gas), saline solutions, and corrosive liquids, also providing anti-sulfide and anti-rust effects. - 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 safety 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 can be made after coating. *We sincerely apologize, but our products are industrial chemical products, and we cannot provide samples for personal use (in the case of non-corporate entities), medical use, or applications involving contact with food.

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).
