[Conformal Coating Example] Preventing Metal Migration on Circuit Boards Due to Moisture
FG-3650 Series
It has four times the moisture resistance of urethane and acrylic, protecting the substrate from moisture and electrolytic solutions with a thin film. It is classified as non-hazardous under the Fire Service Act and does not fall under organic solvents, ensuring high safety.
The conformal coating agent FluoroSurf FG-3650 series has been designed and developed for waterproofing and insulation protection of electronic components, as well as for moisture-proof and waterproof coating of printed circuit boards. It prevents metal migration with a thin film and exhibits protective functions such as moisture resistance, saltwater resistance, water resistance, acid resistance, resistance to lithium battery electrolyte, and water and oil repellency. 【Reasons to Choose FG-3650】 ■ High migration prevention performance ■ Non-hazardous material 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), making on-site management easy ■ Dries at room temperature in a short time, eliminating the need for drying equipment ■ 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) allows for easy application confirmation 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 and keeping the workplace clean. - The pot life is semi-permanent, resulting in no waste. - Repairs can be made after coating. *If you would like a free sample (for corporations only), please include "Sample Request" in your inquiry.

Company information
Our company, Fluoro Technology Co., Ltd., is a specialized manufacturer focused on the following: * Fluorine-based water 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 agile and can respond precisely to your needs. Fluorine-based compounds are available as high-performance materials, but we specialize in room-temperature coatings that possess functions such as water and oil repellency, anti-fouling, moisture resistance, and release properties. We synthesize fluorine resin components in-house to manufacture fluorine-based coatings and water and oil repellent treatments, allowing us to customize resin properties and modify solvent specifications with great attention to detail. 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).
