With the continuous development of automotive electronic technology, more and more complex electronic systems are integrated into vehicles, especially electric vehicles and autonomous vehicle. These systems have extremely strict requirements for the protection of electronic components. In these applications, the fixation and protection of solder joints and circuits are crucial, especially in extreme temperatures and harsh environments. In order to meet these demands, EP 2012 two-component epoxy structural adhesive has become the preferred material for many automotive electronics manufacturers due to its excellent high temperature resistance, adhesive strength, and protective performance for automotive electronic components.
Customer needs and challenges
The client in this case is a leading automotive electronic system supplier, specializing in the development of electric vehicles and autonomous driving technology. The customer’s needs mainly focus on the following aspects:
Solder joint fixation and protection: With the increasing demand for electronic components in automotive electronic systems, especially the complex connections between battery management systems (BMS) and autonomous driving sensors, the stability of solder joints is crucial.
High and low temperature resistance: Automotive electronic products must operate reliably in extreme environments, especially in temperature fluctuations ranging from -40 ℃ to 150 ℃.
Milk white appearance: Due to the long-term use of the product in the car system, it is required that the gel has a milk white appearance in order to efficiently repair and maintain it without affecting the overall visual effect.
Flame retardant performance: In automotive electronics, safety is particularly important, especially in situations such as collisions or battery failures, where flame retardancy is indispensable.
Solution for EP 2012 two-component epoxy structural adhesive
To meet the customer’s requirements, we recommend EP 2012 two-component epoxy structural adhesive. This product is a room temperature/heating cured resin adhesive, particularly suitable for bonding materials such as metals, ceramics, fiberglass, etc., and can work stably in the extreme temperature range of -50 ℃ to 180 ℃. By mixing components A and B in a ratio of 100:45, EP 2012 provides excellent adhesion and anti pollution properties, making it particularly suitable for solder joint protection in automotive electronics.
In practical applications, EP 2012 epoxy adhesive is used for fixing circuit boards and protecting sensor solder joints in electric vehicle battery management systems (BMS). The main reasons why customers choose EP 2012 include the following:
Excellent temperature stability: EP 2012 can withstand drastic changes in car interior temperature, from -40 ℃ to 150 ℃, and maintain stable performance even under extreme temperature differences, avoiding solder joint detachment or protection failure.
Strong adhesion: Even between materials such as metal and ceramics, EP 2012 can still provide a strong bonding effect, ensuring the long-term stability of solder joints and circuit boards.
Flame retardant performance: EP 2012 does not release harmful substances in high temperature environments and has good flame retardancy, effectively preventing fires or safety hazards caused by electrical faults.
Moisture resistance and pollution resistance: For automotive electronics that are exposed to moisture, dust, and other external pollutants for a long time, the protective features of EP 2012 provide great advantages, effectively improving the reliability of the system.
Milk white appearance: The milk white appearance of EP 2012 not only meets the aesthetic requirements of automobiles, but also facilitates maintenance personnel to better identify circuit and solder joint issues during inspection.
EP 2012 two-component epoxy structural adhesive, as a high-performance, high and low temperature resistant, flame-retardant epoxy adhesive, has demonstrated its outstanding advantages in the field of automotive electronics. EP 2012 provides customers with long-lasting and stable protection from solder joint fixation to sensor protection, ensuring the reliability and safety of electronic systems in extreme environments.
