The OPBTM 576 Series is designed for full lamination of optical components in smartphones and large-sized touch displays. This adhesive features an elastic gradient design, providing superior processing characteristics compared to conventional optical adhesives. The high modulus inner layer offers excellent mechanical strength, improving bonding yield and facilitating rework operations. The low modulus outer layer prevents color shift after bonding with the LCD module and excels in ink gap filling.
Thick OCA for Industrial Control Applications, OpticPB™ 17E Series, designed for full lamination of industrial computers and industrial touch displays.
