OCA Optically Clear Double Sided Adhesive Tape For Touch Panel Descriptions: OCA(Optically Clear Adhesive) double sided tape are highly specialized optically clear free-film adhesives offering superior clarity and excellent adhesion to various types of transparent substrates. They are easy to convert and are contaminant-free, resulting in improved bubble resistance in laminations exposed to high temperature and high humidity. Common applications include displays, touch panels and others requiring an optically clear bond. Features: Superior transparency. Very little change in appearance even when exposed to light or in a hot and humid climate. Suitable for bonding materials such as glass and polycarbonate to plastics. Manufactured in a clean room. Outgassing of plastics such as polycarbonate controls bubble formation and allows ink to follow uneven surfaces. Applications: Touch screens- for bonding film and glass laminates. Avionics/military displays. Transparent graphic overlays. Optical management films for LCD. Projection screens.
