LOCA Adhesives for Display Assembly 

Controls for electronic and electrical products used in consumer and industrial markets are rapidly converting to display and touch screen panel (TSP) technologies. Ease of use and cost are two major drivers for the change.

Production efficiency and higher throughput are always high on manufacturer’s “wish lists”. For bonding technology leaders like Panacol-USA, it becomes imperative to develop faster curing, liquid optically clear adhesives (LOCA) that can be produced in a range of viscosities to accommodate the numerous production processes associated with display and touch screen panel assembly. Panacol-USA’s optically clear adhesives are solvent-free, single component, and cure in seconds under low intensity UV or Visible light. They can be seamlessly integrated into existing production lines to quickly maximize their contribution to increased productivity.

Panacol-USA manufactures optically clear coupling adhesives for attaching glass and polymer-based touch screen panels. They possess extreme softness, clarity, flexibility, and resistance to thermal cycling. In addition, the adhesives’ flow properties and ability to minimize air entrapment eliminate ripples, providing optimal image transmission.

LOCA adhesives featuring a dual curing component which reacts to atmospheric moisture are also available. Thus shadow zones within the display frame can also be cured reliably.
