Product Details Key Industries Related Products

Optically Clear Adhesives (OCAs) are highly transparent adhesives used to bond visually clear components without bubbles or distortion while still transmitting as much light as possible through optimal refraction. OCAs can improve contrast ratio and optical clarity while reducing the amount of reflected light, which improves the viewability and readability of LCD, LED, and OLED screens.

These adhesives are used specifically for their superior optical and mechanical attachment qualities. Assemblies utilizing OCAs benefit from high adhesion and peel strength. Optically Clear Adhesives have high dimensional stability, low shrinkage, and resist whitening overtime. Integrating layers with the right Optically Clear Adhesive enables rugged, long lasting bonds in complex assemblies.

OCAs are a key component in advanced displays, touch panels, and touch screens found in a wide range of applications. These adhesives are used to bond multiple layers of touch screens from the backlight, to liquid crystal display, to the capacitive touch panel, and to the protective cover.

Optically Clear Adhesives come in a variety of formulations to accommodate a broad array of adhesion applications. OCAs are typically composed of acrylic, polyvinyl acetate (PVA), polyurethane (PU), silicone, or epoxy.

OCAs can bond a variety of materials together but are typically used on polyethylene terephthalate (PET), acrylic polymethyl methacrylate (PMMA), indium tin oxide (ITOs), and glass.
