Optically Clear Adhesive
Yih Hwa Optically Adhesive is one of the key raw materials used in touchscreens. It is made from optically clear acrylic adhesive without a carrier (substrate). Release films are laminated on both the top and bottom surfaces, forming a substrate-free double-sided adhesive tape.
YWT-1039OCA is a high-performance Optically Clear Adhesive (OCA) tape specifically engineered for touchscreen manufacturing and display bonding. Unlike standard double sided tape, this substrate-free tape consists purely of a specialized optically clear acrylic adhesive layer, ensuring maximum transparency.
• Superior Clarity: Eliminates the haze or yellowing often found in layered substrates.
• Thin Profile: Ideal for ultra-thin display stacks in smartphones, tablets, and kiosks.
• High Bond Strength: Delivers a durable, bubble-free bond between glass, plastic, and ITO film layers.
Applications
• Bonding of transparent components, and projection screen assembly.
• Assembly of aerospace or military optical devices.
• Display module assembly and lens bonding.
• Lamination of touch panels, panels, icons, and plastic materials such as glass and related substrates.
