With the continuous development and application of energy storage technology, the reliability of electronic products, especially battery management systems (BMS) and energy storage modules, has become a key concern in the industry. In the production process of these devices, the packaging and sealing of PCBA (printed circuit board components) are particularly important. In order to cope with various challenges in different work environments, choosing the appropriate sealant has become particularly crucial. This article will focus on introducing two high-performance sealants: SIPC 9200 dam sealant and SIPC 9400 potting sealant, and how they meet the special needs of the energy storage PCBA field.
Special requirements for sealing of energy storage PCBA dam
The PCBA of energy storage devices often faces multiple external pressures such as high temperature, moisture, chemicals, and vibration during use. Therefore, dam sealant should not only have excellent adhesion and sealing performance, but also be able to withstand long-term environmental pressure to ensure the stability and long-term durability of electronic components.
Customer requirement: The energy storage PCBA dam sealant needs to meet the following requirements:
Flame retardancy: Energy storage equipment may generate heat and even pose a risk of short circuit during operation, so the sealant must have a certain degree of flame retardancy to ensure the safety of the equipment.
Rapid initial setting: In the production process, the initial setting speed of sealant is very important. In order to improve production efficiency, the sealant should be able to reach the initial solidification state within 20 minutes.
Not poisoned by acrylic three proof paint: Acrylic three proof paint is commonly used as a protective coating for electronic components. If the sealant reacts chemically with the three proof paint, it may affect the quality of the paint film. Therefore, it is required that the sealant be compatible with acrylic three proof paint.
Compatibility of subsequent processes: The sealant must be able to meet the requirements of subsequent processes, such as dispensing, welding, etc., without interfering with the subsequent processing flow.
To address these issues, SIPC 9200 and SIPC 9400 two-component silicone rubber sealants have emerged, demonstrating excellent performance in the field of energy storage PCBA dam sealing.
SIPC 9200 dam sealant: comprehensive improvement in flame retardancy, thermal conductivity, and adhesion performance
SIPC 9200 is a high-performance silicone adhesive sealant, characterized by flame retardancy, good thermal conductivity, and excellent adhesion. This product is particularly suitable for dam sealing of energy storage PCBA, and its excellent performance can effectively improve the reliability of energy storage equipment.
The main advantages of SIPC 9200
Flame retardant certification: SIPC 9200 has passed UL 94V-0 flame retardant certification, ensuring that it can provide sufficient safety protection in high temperature and fire source environments.
Excellent thermal conductivity: This adhesive has excellent thermal conductivity and can help dissipate heat from electronic components, thereby improving the efficiency and lifespan of equipment.
Chemical resistance and adhesion: SIPC 9200 has strong adhesion to most metals, plastics, and other materials, as well as strong resistance to external substances such as chemicals, moisture, and dirt, effectively protecting electronic components from corrosion and pollution.
Excellent aging performance: SIPC 9200 has excellent weather resistance, especially suitable for long-term use in outdoor and harsh environments, with a service life of up to 20 years.
Seismic resistance and electrical insulation performance: The cured SIPC 9200 exhibits excellent seismic resistance and electrical insulation performance, effectively reducing the impact of factors such as thermal shock and vibration on the equipment.
These excellent features make SIPC 9200 an ideal choice for energy storage PCBA dam sealing, providing long-term stable protection for energy storage equipment.
SIPC 9400 sealant: two-component silicone rubber, fast curing, widely applicable
SIPC 9400 is a two-component condensation type adhesive sealing silicone rubber that uses room temperature rapid curing technology. It not only has extremely strong adhesion, but also can complete deep curing in a short time, which is very suitable for the encapsulation application of energy storage PCBA.
The main advantages of SIPC 9400
Two component system, easy to mix: SIPC 9400 adopts a 2:1 volume ratio mixing method, allowing for large mixing ratio errors, simple operation, and is suitable for most dispensing equipment.
Fast curing, saving time: Compared with traditional silicone, SIPC 9400 can cure quickly at room temperature, reducing production cycles and greatly improving production efficiency.
Good resistance to cold and hot alternation: SIPC 9400 has excellent resistance to cold and hot alternation, and can maintain stable adhesion and sealing effect in harsh temperature changing environments.
Excellent electrical insulation performance: The cured SIPC 9400 has excellent electrical insulation performance, which can effectively prevent leakage and improve the safety of energy storage equipment.
Environmental halogen-free certification: Complies with environmental standards such as ROHS, halogen-free, REACH, etc., ensuring the safety and environmental friendliness of the product.
Strong compatibility: SIPC 9400 has good adhesion to most common materials such as metals, plastics, ceramics, etc., and does not require additional primer treatment, making operation easier.
Therefore, SIPC 9400 is not only suitable for sealing energy storage PCBA, but can also be widely used for sealing and protecting other electronic components, especially in high temperature and humid environments.
Strong alliance between SIPC 9200 and SIPC 9400
In the production process of energy storage PCBA, the strong combination of SIPC 9200 and SIPC 9400 can leverage their respective advantages and achieve twice the result with half the effort.
Energy storage PCBA dam sealant
Perfect cooperation, forming dual protection: SIPC 9200, as a dam sealing adhesive, can provide strong external protection for energy storage PCBA, preventing damage to equipment caused by fire, thermal shock, and mechanical vibration. SIPC 9400, on the other hand, serves as a potting adhesive that quickly solidifies and provides deep encapsulation for internal components of the equipment, avoiding electrical short circuits, leakage, and moisture intrusion, thereby enhancing overall stability and reliability.
Rapid production and efficient construction: Both products support rapid curing and will not undergo chemical reactions with acrylic three proof paint during application, avoiding poisoning and secondary pollution. In this way, while improving production efficiency, it also ensures the smooth progress of subsequent processes.
Strong environmental adaptability: Whether in high-temperature environments or areas with high humidity, SIPC 9200 and SIPC 9400 can maintain excellent performance, providing long-term protection for energy storage devices and ensuring their safety and reliability under extreme conditions.
The best choice for providing comprehensive protection for energy storage PCBA
The strong combination of SIPC 9200 and SIPC 9400 provides comprehensive protection for the sealing of energy storage PCBA, thanks to their excellent flame retardancy, thermal conductivity, adhesion, electrical insulation, and rapid curing advantages. These two high-performance silicone rubber sealants not only meet high environmental adaptability requirements, but also improve production efficiency and reduce production costs. Whether it is dam sealing or grouting, the combination of SIPC 9200 and SIPC 9400 provides a more stable, safe, and durable solution for energy storage equipment.
