Devcon® Tru-BondTM PSA LOCA products provide a unique patent pending chemistry engineered to bond the glass cover lens to touch panel sensors and touch panel assemblies to the LCD or OLED module. The product is applied as a liquid and cured using a single exposure step to form a fully polymerized pressure sensitive adhesive (PSA). The pressure-sensitive adhesive can then be laminated to the mating surface.

This single light exposure design delivers consistent strengths under the inked glass areas and through to the clear lens portions of the assembly. The Devcon® Tru-Bond™ PSA LOCA product line can bond to a wide range of materials including glass, PMMA, ABS, PP, PE, PC and many more
surfaces.
