In the modern automotive industry, the reliability of sensors and wiring harnesses is crucial for the performance and safety of the entire vehicle. Especially temperature sensors, they need to maintain efficient and stable operation in harsh working environments, while the tail harness is responsible for transmitting signals to the onboard control system. Therefore, the sealing protection of temperature sensors and tail wiring harnesses is particularly important. In this case study, Yilian will explore an innovative encapsulation solution that solves the problems of temperature resistance, waterproofing, moisture resistance, and electrical insulation of temperature sensors and tail wiring harnesses in working environments.

background
With the increasing dependence of the automotive industry on electronic technology, temperature sensors have become an indispensable part of automotive electronic systems. These sensors typically need to be installed in engines, exhaust systems, or other high-temperature areas, and have high tolerance requirements for environmental conditions such as temperature, humidity, and mechanical shock.
At the same time, the rear wiring harness of the car also bears the responsibility of transmitting sensor data to the central control system. Due to the long-term exposure of vehicles to high temperatures, high humidity, and other harsh environments, wiring harnesses require good sealing and protection to ensure their stability during long-term use.
In order to ensure the stable operation of these sensitive components, encapsulation technology has become an ideal solution. Sealing materials can provide sealing protection for temperature sensors and tail wiring harnesses, preventing external factors from affecting electronic components. Traditional sealing materials may have certain limitations in terms of fluidity, curing time, and temperature resistance, so it is particularly important to choose a high-performance sealing adhesive.
Challenge
When selecting sealing materials for temperature sensors and tail wiring harnesses, the main challenges are as follows:
Temperature resistance performance
Temperature sensors often operate in high-temperature environments, especially near the engine, where the operating temperature can reach up to 120 ° C, or even up to 150 ° C in a short period of time. Therefore, the sealing material must have good high temperature resistance to ensure long-term stable protection.
Solution
Based on the above requirements, we recommend using EP 1712A/B two-component solvent-free ambient temperature curing epoxy potting material (referred to as 1712BG). EP 1712BG has excellent performance and can meet various needs during the sealing process of temperature sensors and tail wiring harnesses. After mixing, the flowability is moderate, it has certain leak proof characteristics, and has a wide range of adhesiveness. The cured product meets the flame retardant requirements of UL 94V-0. Suitable for packaging protection of automotive electronics, sensors, optoelectronic LEDs, and lighting products.
Product features:
▶ Good toughness and high hardness
▶ Excellent adhesion and cracking resistance
▶ Excellent electrical insulation and stability stability
▶ Good waterproof and moisture-proof properties, with extremely low water absorption rate
▶ Good temperature resistance, able to withstand temperatures up to 150 degrees Celsius in a short period of time

Challenge
When selecting sealing materials for temperature sensors and tail wiring harnesses, the main challenges are as follows:
High liquidity requirements
The sealing material needs to have good fluidity to ensure complete coverage and filling of gaps around sensors and wiring harnesses, thereby providing effective sealing protection. However, materials with high fluidity may not maintain sufficient adhesion during the curing process, affecting the protective effect.
Room temperature curing
Due to the fact that the sealing process of temperature sensors and tail wiring harnesses usually needs to be carried out on the production line, it is very important to choose a room temperature curing sealing adhesive. Room temperature curing can not only reduce energy consumption during the production process, but also avoid component damage caused by high-temperature curing.
Moderate curing time
Excessive curing time may affect production progress, while insufficient curing time may result in incomplete sealing and insufficient protection. Therefore, choosing a material with a moderate curing time is crucial.
