[Conformal Coating Example] Preventing Metal Migration on Circuit Boards Due to Moisture
It has four times the moisture resistance of urethane and acrylic, and protects the substrate from moisture and electrolytic solutions 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 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 unnecessary ■ 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 from 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 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 service law regulations. - It has low viscosity and is easy to handle, keeping the workplace clean. - The pot life is semi-permanent, eliminating waste. - Repairs can be made after coating. *If you would like a free sample (limited to corporations), please include "Sample Request" in your inquiry.
