Moisture-proof coating agent, significant reduction in management items, non-flammable, solvent-free.
FG-3650 Series
Moisture-proof coating agent for room temperature drying type printed circuit boards (conformal coating agent) that takes into account safety, workplace environment, and performance.
The protective coating agent for electronic substrates (conformal coating) "FloroSurf FG-3650 series" is suitable for waterproofing and insulation protection of electronic components, as well as for moisture-proof and waterproof coatings of mounted substrates. It is non-flammable and does not fall under the category of organic solvents, thus exempt from regulations under the Fire Service Act and the Industrial Safety and Health Act. Additionally, it does not use PFAS regulated substances, significantly reducing management items in the workplace. Furthermore, compared to urethane, acrylic, and silicone-based coatings, it exhibits 3 to 10 times greater moisture resistance (at the same film thickness) while providing protective functions such as moisture resistance, saltwater resistance, water resistance, acid resistance, resistance to lithium battery electrolyte, and water and oil repellency. 【Benefits in the Manufacturing Site】 ■ Safe to use as it is a non-flammable, low-odor liquid → It is safe as it is non-flammable. Exempt from Fire Service Act regulations. No need for hazardous material storage, hazardous material handling manuals, or explosion-proof equipment, and quantity management is unnecessary. ■ Not classified as an organic solvent under the Industrial Safety and Health Act → Management items such as workplace environmental measurements and organic solvent health checks for workers are no longer necessary. ■ Completes drying at room temperature in 5-20 minutes after application → No special equipment such as heating furnaces is required. ■ Low viscosity makes it easy to handle. The workplace remains clean. ■ The pot life is semi-permanent. Zero waste. ■ Repairs are possible after coating.

basic information
【Performance Features】PFAS-regulated substances are not used. ■ Higher moisture and water resistance compared to other resins. → Exhibits 4 to 10 times greater moisture resistance than urethane, acrylic, and silicone-based moisture-proof coatings at the same film thickness. Helps reduce weight increase due to the coating film, contributing to the lightweighting of mobile devices. ■ High resistance to acidic substances such as lithium battery electrolytes. → Can protect the substrate in case of electrolyte leakage, preventing fire accidents. ■ Provides strong protective effects against acidic gases, saline solutions, corrosive liquids, and hydrogen sulfide. Prevents metal corrosion. ■ Does not contain unreacted low molecular weight compounds like silicone or UV-curable types, so it will not cause contact failure at electrical contacts or film peeling after application. ■ The coating has flame retardancy equivalent to UL94-V0. ■ A model with fluorescent dye for application confirmation is also available. Free samples are currently being offered (please only bear the shipping cost; shipped cash on delivery).

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).
