Panasonic's new "Time-lagged UV Curing Adhesive" makes the assembly process of parts and materials easier as it cures slowly after UV irradiation.
Osaka, Japan - Panasonic Corporation announced today that it has developed a "Time-lagged UV Curing Adhesive  (Fine Glue)" suitable for gluing and assembly of mobile device housings and panels, and will start mass-producing it in September 2016. This liquid material cures after a certain amount of time following exposure to UV irradiation, making it easier to carry out the assembly process and rendering it possible to attach a UV-protection (UV-proof) panel after irradiation. As this new adhesive can be applied in a thin width and thick layer, it is suitable for mobile devices that have limited space for adding adhesive.
There are various challenges faced by conventional adhesives. For example, double-sided tapes currently used to bond the display panel to the housing of a mobile devices or camera are difficult to be applied on a small area. Thermoset adhesives  take a long time to cure in a high temperature environment, whereas fast UV curing adhesive cures so quickly after irradiation that it cannot attach a UV-protection panel to the housing. By developing a unique resin design technology, Panasonic has created a new adhesive product capable of curing after a certain period of time following exposure to ultraviolet irradiation. The extra time before curing enables the position of parts and materials to be adjusted and makes it possible to apply the adhesive to attach materials that do not transmit ultraviolet light. The product is also suitable for quick application on a small area in a low temperature environment.
Gluing the housing and display panel, gluing films that do not transmit much UV, camera module assembly, gluing a cover glass or a back light, and the assembly of wearable devices
