3M offers an array of lighter, thinner, state-of-the-art optical bonding solutions. You can use them to bond and shape our optical display films without adversely affecting the visual quality of the display, and they can be used in LCD or OLED designs. Our optically clear adhesives offer easy application, consistent quality assurance, and large-scale manufacturing capability.
These film-based adhesives are a great choice for touch screens and for bonding film to glass. 3M OCAs come in a variety of thicknesses and are precision-manufactured to eliminate common adhesive visual defects such as bubbling and mura which can distort the display—and diminish consumer satisfaction with your product. 3M OCAs help improve the clarity, color neutrality, and reliability of a display. Avionics and military displays often use 3M OCA for reliability, quality, and durability of design.
3M pLOCA is a high viscosity liquid adhesive designed for gap filling of touch module assemblies or direct display bonds or other applications that require optical bonding. Gap filling reduces reflection and increases light transmission at touch panel/display interfaces.
3M pLOCA offers both low modulus and low shrinkage of the UV-cured adhesive to reduce stress-induced defects in the display appearance. It can be applied in both a vacuum system, as well as a vacuumless lamination process. It’s a thixotropic (shear thinning) material that provides a wider coating process window, improved manufacturing efficiency, better dimensional control, and higher integrator yields.
