Devcon® Tru-BondTM PSA LOCA products provide a unique patent pending chemistry engineered to bond the glass cover lens to a 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.
