Display Bonding
With the ever increasing digitalization in all areas of our lives, more and more displays and touch screens are being used. In addition to smartphones, tablets and television screens almost every modern household appliance including washing machines, dishwashers, and refrigerators nowadays feature a display.
The requirements for high end displays are high: Reading must be comfortable, they must be shatter-proof, and they must maintain their clarity for the life of the products. This is particularly challenging for displays in cars and smartphones or cameras as they are expected to be non-yellowing despite the influence of sunlight and other climate stresses. Specially formulated optical adhesives from Panacol are designed to be optically clear and non-yellowing (LOCA=liquid optically clear adhesives). They are flexible enough to provide the ability to intercept thermal stresses between dissimilar substrates and to reduce Mura defects. The adhesives exhibit excellent adhesion to ITO coated glass, PMMA, PET, and PC and cure within seconds under UV irradiation. Dual curing adhesives are available which react to atmospheric moisture and will cure reliably in shadowed zones within the display frame.
To protect displays from external influences such as atmospheric humidity, dust and cleaning agents Panacol form-in-place-gaskets (FIPG) can be used for simultaneous bonding and sealing of displays and touchscreens.
