Liquid Optically Clear Adhesives LOCA are primarily used in the electronics industry for bonding displays to touch panels or cover lenses. They play a crucial role in devices where the clarity of the adhesive is essential for the function and aesthetics of the device, such as smartphones, tablets and touchscreen devices. Offering specialty monomers, oligomers and dielectric resins designed for high-performance. CN and CN impart excellent adhesion and flexibility to laminating and pressure sensitive adhesive formulation, especially those for glass.

Liquid optically clear adhesive

Liquid optically-clear adhesive LOCA is liquid-based bonding technology used in touch panels and display devices to bind the cover lens, plastic, or other optical materials to the main sensor unit or each other. These adhesives improve optical characteristics and durability. LOCA glue is often hardened using ultraviolet light. LOCA also allows for thinner designs and new technologies, such as the use of silicone, that improve the properties of the final product. Optical bonding , including LOCA and non-liquid OCA tape, are used in a wide range of electronic equipment, especially those with touch panels. The adhesive bonds the touch panel to the main liquid crystal display, and also bonds any protective cover, such as the lens, to the touch panel. After application, the adhesive is cured onto the device through ultraviolet light UV , heat, moisture, or a combination, depending on the manufacturer and specifications. Major applications include capacitive touch panels, 3D televisions 3D TV , and glass retarders. Optical bonding improves optical performance of displays. Optical bonding improves the contrast ratio by reducing the amount of reflected light, thus improving viewability. This is especially important in outdoor applications, where direct sunlight can decrease viewability.
