Optically Clear Adhesives (OCAs) are highly transparent adhesives used to bond visually clear components into an optically clear lamination without bubbles or distortion. OCAs enable complex optically clear laminations to transmit 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 using optically clear laminations.
These adhesives are used specifically for their superior optical and mechanical attachment qualities. Optically clear laminations 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 optically clear laminations.
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 into an optically clear lamination, securely joining components such as touch screens, backlights, liquid crystal displays, capacitive touch panels, and protective covers.
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. Optically Clear Adhesives effectively combine these engineered materials to create a unique optically clear lamination tailored to your application.
