The selection of thin-layer sealing materials is crucial in the signal module protection of smart water meters. It not only needs to provide good sealing protection, but also needs to meet the requirements of rapid curing, flame retardancy, and temperature resistance to ensure stable operation of the water meter in different environments. EP 2025FR epoxy resin is an excellent solution for this application requirement. This article will delve into the requirements for thin-layer encapsulation of water meter signal modules and the product features and advantages of EP 2025FR.
Key requirements for thin-layer sealing of water meter signal module
The water meter signal module is usually exposed to various outdoor environments, such as humidity, high temperature, low temperature, etc. Therefore, the sealing material needs to have the following characteristics:
- Rapid curing at room temperature to improve production efficiency
In the production process of water meters, the curing time of the sealing material directly affects production efficiency. Traditional epoxy resins may require longer curing times, while EP 2025FR uses a room temperature curing system that can quickly cure at room temperature without the need for additional heating equipment, greatly improving production efficiency and making it suitable for large-scale assembly line operations. - Flame retardant properties ensure safe use
The water meter signal module usually involves electronic components such as circuit boards, which are susceptible to electrical short circuits or external environmental influences. Therefore, the sealing material must have good flame retardant properties. EP 2025FR meets the UL 94 V-0 flame retardant standard, which can effectively reduce the risk of fire and improve the safety of water meters in harsh environments. - Temperature resistance and adaptability to different climatic conditions
The water meter needs to operate normally at an ambient temperature of -20 ℃~60 ℃, therefore, the sealing material should have excellent temperature resistance. EP 2025FR has good low-temperature flexibility and high-temperature stability, and even at extreme temperatures, there will be no cracking, detachment, or performance degradation issues, ensuring long-term stable operation of the water meter.
Application Example of EP 2025FR in Thin Layer Sealing of Water Meter Signal Module
In practical applications, a water meter manufacturer chose EP 2025FR for signal module encapsulation, with the main goal of improving protection performance and optimizing production processes. After testing, the manufacturer found that:
Fast curing speed: The original 24-hour curing time has been shortened to 3-5 hours, greatly improving production efficiency;
* Strong adhesion: EP 2025FR is firmly bonded to the surface materials of the signal module (plastic, PCB board) and is not easily peeled off;
* Strong environmental adaptability: Within the temperature range of -20 ℃ to 60 ℃, there was no cracking or detachment of the sealing layer;
* Significant flame retardant effect: compliant with UL 94 V-0 standard, enhancing the safety of the water meter circuit board. EP 2025FR epoxy resin is an ideal material for thin-layer sealing of water meter signal modules due to its rapid curing at room temperature, strong flame retardancy, excellent temperature resistance, and good toughness. Whether it is improving production efficiency, enhancing product reliability, or reducing fire risks, EP 2025FR can meet the stringent application requirements. If you are looking for a high-performance water meter sealant, EP 2025FR is undoubtedly a worthwhile choice to consider. label: PCB encapsulation, water meter signal module encapsulation, epoxy encapsulation adhesive, power module encapsulation
