Henkel Corporation (Rocky Hill, CT) has introduced next generation Loctite® Liquid Optically Clear Adhesives (LOCA) that increase display durability, improve contrast ratio, reduce power consumption, and enable thinner device designs, says the company. New adhesives for direct bonding and cover lens bonding simplify display assembly, while advanced cleaners reduce the overall manufacturing cost with more effective manual and automated rework cleaning processes. Loctite ultra-soft LOCAs for direct bonding reduce the potential for MURA, while filling gaps from 200 to 300 microns. Loctite 3191™, 3198™ and 3199™ are low durometer, low modulus and low shrinkage materials that also deliver high tensile and adhesion strength on polarizer films, PMMA, glass and ITO-coated glass to prevent delamination during RA testing.
