How to choose reverse radar sealant? PUR 1670 provides comprehensive protection for your radar system

With the development of the automotive industry, reverse radar, as an important technology to improve driving safety, has become a standard configuration for modern cars. The reversing radar system detects obstacles behind through sound wave reflection, promptly alerting the driver, reducing blind spots during reversing, and improving driving safety and convenience. However, with the continuous advancement of automotive technology, reverse radar systems not only need to have accurate detection functions, but also face more stringent working environments and increasing durability requirements. In order to ensure the stability and long-term reliability of the reverse radar in various complex environments, the application of sealant has become increasingly important. The working environment and requirements of reverse radarThe reverse radar system is usually installed on the rear bumper of a car, especially the radar sensor part, which is directly exposed to the external environment. These sensors must operate normally under different climatic conditions, whether in high temperatures, hot summers, cold winters, or even harsh weather conditions such as rain, snow, and freezing, they need to maintain high reliability and stability.In order to ensure the long-term effective operation of the sensor, the electronic components of the reverse radar need to be packaged and protected. This is because:Moisture protection: Radar sensors are susceptible to external environmental factors such as rain, snow, and moisture, which can cause short circuits or damage to the circuit board.Shock and pressure resistance: Radar sensors are subject to varying degrees of mechanical impact and vibration, especially during parking or reversing, which may cause damage to the sensors.High temperature resistance: In the high-temperature environment outside the car, electronic components need to be able to withstand sustained high temperatures without affecting performance.PUR 1670A/B is a two-component solvent-free room temperature or heat cured resin elastomer composite used in two-component sealing, filling, flame retardant, thermal conductivity…
