Screen bonding adhesives often yellow and shrink after long-term use, not only affecting display appearance but also causing edge lifting and delamination—especially in devices like automotive displays exposed to prolonged UV radiation, where yellowing and aging are even more pronounced. A UV-curable silicone-based liquid optical adhesive, with a yellowness index below 0.1 and an ultra-low shrinkage rate of less than 0.1%, combined with excellent UV aging resistance, acts as a "freshness guardian" for screen bonding. It keeps displays clear, edge-lift-free, and in perfect condition—even after years of use.

Its core strengths lie in yellowing resistance and UV aging resistance. With a yellowness index below 0.1, the adhesive remains virtually colorless and transparent over time, avoiding the gradual yellowing that plagues traditional bonding adhesives—even under prolonged sunlight or UV exposure. Its outstanding resistance to UV degradation prevents embrittlement, cracking, or aging, making it especially suitable for outdoor-exposed displays such as automotive center consoles and outdoor digital signage.

The ultra-low shrinkage rate of <0.1% solves a major pain point in screen bonding. After curing, the adhesive exhibits virtually no shrinkage, maintaining tight contact with the screen substrate without edge lifting, gaps, or delamination. This eliminates dust ingress and moisture penetration caused by adhesive contraction. The gel-like cured texture also provides excellent flexibility, accommodating slight thermal expansion and contraction during screen operation, preventing stress cracking and further enhancing long-term bonding durability.

While delivering exceptional stability, its optical performance remains outstanding. With 99% light transmittance and haze below 0.1%, it preserves pristine display clarity, while strong adhesion ensures lasting bonding reliability. Whether for long-life consumer touchscreens, sun-exposed automotive displays, or high-frequency commercial LCD panels, this UV adhesive keeps screen bonding "fresh" over time, significantly extending display service life.
