SIPA 1830(H50) Vehicle Display Frame Bonding Solution
— Effectively addressing the challenges of debonding and light leakage With the rapid development of smart cockpits, in-vehicle displays are evolving towards larger sizes, narrower frames, and higher brightness. The increasingly sophisticated structure of display modules poses higher demands on frame bonding materials. Once the bonding fails, it can lead to light leakage and abnormal noise at the least, and debonding and reliability failure at the most, directly affecting the overall quality of the vehicle. Common challenges in the display bonding industry: In the bonding of in-vehicle display frames, manufacturers generally face the following issues: The alternating temperature changes cause a significant temperature difference in the interior environment of the degumming vehicle, and ordinary glue is prone to stress concentration due to thermal expansion and contraction. The adhesive layer hardens, resulting in insufficient flexibility of the light-leaking colloid, which cannot absorb structural deformations, leading to changes in the frame gap.The pollution caused by the by-products of curing manifests as white mist volatilizing during the curing of glue in certain display areas, affecting the optical display effect.The long-term aging reliability is insufficient, and there is a significant performance degradation under high temperature, high humidity, and electrical environments.Recommended solution: SIPA 1835 (H50) RTV SIPA 1830A/B two-component addition-type silicone adhesive SIPA 1835 (H50) is based on the RTV SIPA 1830A/B two-component addition-type silicone system, specifically designed for bonding automotive electronics and display structures. It ensures high bonding strength while providing long-term stable elastic cushioning capability. This product can be cured at room temperature and also supports rapid curing through heating, making it suitable for automated production lines. During the curing process, no by-products are volatilized, and the volume change is minimal, making it extremely friendly to precision display modules. The core product features a two-component addition-type system (1:1 mixture) with simple metering and…
