Our LOCA adhesives are distinguished by their unique combination of high bond strength AND low refractive index. The LOCA products exhibit strong adhesion to various substrates, including glass, PMMA, PET, PC, and metals. 

These adhesives remain tacky even after full curing, and therefore they are intended to be used as lamination adhesives, between optical films and other flat surfaces. The low index enables bonding between layers while keeping the light from leaking between adjacent layers. For example, it is possible to attach a diffuser film to a light guide without degrading the light guiding capability.
