[Examples of Acid Gas Countermeasures] Strongly protects printed circuit boards from acidic gases and moisture.
FG-3650 series
It has four times the moisture resistance of urethane and acrylic, and protects the substrate from acidic gases 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 conformal coating agent FluoroSurf FG-3650 series has been designed and developed to protect printed circuit boards from acidic substances (such as hydrogen sulfide gas and lithium battery electrolyte). It provides strong protection for metals against acidic gases and liquids with a thin film, ensuring long-term protection for printed circuit boards. 【Reasons for choosing FG-3650】 ■ High protective performance ■ Non-hazardous under the Fire Service Act, so explosion-proof equipment and quantity management are not required ■ Not classified as an organic solvent (under the Industrial Safety and Health Act), so environmental measurements and organic solvent health checks for workers are not necessary, making on-site management easier ■ Dries at room temperature in a short time, no drying equipment required ■ Low odor *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, 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 model with fluorescent dye (optional) makes it easy to confirm application under black light. - It is low in toxicity and is not subject to PRTR law or fire safety regulations. - It has low viscosity, making it easy to handle. It does not dirty the workplace. - The pot life is semi-permanent, resulting in no waste. - Repair is possible 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 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).
