LOCA液態(tài)光學(xué)膠-觸摸屏接著應(yīng)用材料
UV-5352-2液態(tài)光學(xué)膠可接著於玻璃輿ITO玻璃接著應(yīng)用,以提高顯示器對(duì)比。輿傳統(tǒng)採(cǎi)用空氣間隙的方法相較,LOCA液態(tài)光學(xué)膠可抑制外部光照輿背光等遵致的光散射情況。
迅速反應(yīng)成型的LOCA液態(tài)光學(xué)膠具有輿玻璃相近的折射率及穿透率、耐黃化、且具有良好的可撓性,能夠接合熱膨脹系數(shù)差異很大的兩種材料,可抵擋貼合時(shí)高低溫變化產(chǎn)生的問(wèn)題。
LOCA液態(tài)光學(xué)膠優(yōu)點(diǎn)Advantage
因消除空氣間隙使得模組空間更薄Thinner sizing by eliminating air gap
面板承受力度增加lncrease the panel strength
因可控制折射率,使得書(shū)面亮度興對(duì)比度增加lincrease brightness﹠Contrast by refractive index control
面板可視角度增加lncrease the viewing angle
更可減少成本支出Reduce costs
產(chǎn)品特色:Feature
(1)UV固化后具有高透光性、高折射率、低收縮等特點(diǎn)The cured adhesive exhits high transparency,high refractive indexand low volme shrinkage
(2)本產(chǎn)品有很好的柔軟延展性,適合不同膨脹系數(shù)材質(zhì)接著When cured,the flexibility of LOCA makes it ideal for applications involving dissimilar surferces where thermal coefficient of expansionmay be a problem
(3)通過(guò)信賴(lài)性測(cè)試,溫低溫循環(huán),高低溫沖擊,高溫高濕 ,高溫烹煮Pass environmental test experiments,such asch as thermal cycle,thermal shock,high temp.+high humidity,pressure cook.
