Optically Clear Adhesive
For 4- to 15-inch displays from cell phones to monitors, a new Loctite® Primer and Liquid Optically Clear Adhesive (LOCA) combination from Henkel Corporation (Rocky Hill, CT) cures in less than 90 minutes in shadowed areas where light cannot penetrate during UV cure processes. Formulated for direct bonding, Loctite® 7389™ Primer and Loctite® 3196PR™ LOCA provide a solution for the cure through depth limitation of side curing, the work-in-process and potential damage to the LCD of heat curing, and the long cure time required for moisture cure. To fully leverage existing equipment, a simple, low-cost workstation positioned before lamination precisely and rapidly dispenses the primer and requires no modification or adjustment of the laminating process, says the company.
