PERMABOND UV648 is a UV-curing adhesive developed for use on plastics. It has superb adhesion to acrylic and contains a long-wavelength photo initiator to allow it to cure through UV-stabilised plastics. This adhesive can also be used to bond glass, metals and other materials. UV648 cures to give a colourless bond so is ideal for applications where aesthetic appearance is vitally important.
