Is it difficult to bond car touch screens? A RTV silicone solution makes it easy for you to handle!

With the rapid development of intelligent cockpit technology in automobiles, the touch screen of the vehicle’s central control has become the core of human-machine interaction. Whether it’s entertainment, navigation, air conditioning, or vehicle settings, a high-definition large screen carries more and more functions. However, the structural bonding technology behind the large screen is often overlooked. Today, we focus on a specific application point – the bonding problem between the screen film and aluminum frame of car touch screens, and bring a professional grade adhesive to solve such challenges: RTV SIPC 1822. Adhesive bonding of car touch screen1、 The challenge of bonding the structure of car touch screensIn the car display system, multi-layer composite structures such as touch glass, polarizing film, and conductive film need to be assembled onto aluminum alloy structural components through precision bonding. There are many technical challenges faced in this process:Limited bonding width: Due to appearance and structural design, the bonding surface of the screen frame is often only about 3mm, and the shear strength and initial bonding force of the adhesive must be excellent.High and low temperature impact: The temperature fluctuation of the car interior environment is large, ranging from minus 40 ℃ to 90 ℃ or even higher under sunlight exposure, requiring the colloid to have good thermal stability and low-temperature flexibility.High durability requirements: The vehicle’s lifespan starts at 10 years, and the adhesive needs to withstand long-term comprehensive environmental tests such as UV, moisture, vibration, dust, etc.Safety and Environmental Protection: The release material must be low volatile and non corrosive, especially not have a negative impact on materials such as PC and copper, and must comply with EU environmental regulations such as ROHS and REACH.2、 Solution recommendation: RTV SIPC 1822In response to the above challenges, we recommend using RTV SIPC 1822 neutral dealcoholized silicone…
