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.
- Cure on demand
- Non-drip
- High shear strength
- Fast curing with low-power lamps
- 100% solids, no solvents
- Excellent adhesion to plastics
