Description
PERMABOND UV632 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 is also great to bond glass, metals and other materials. UV632 cures to give a colourless bond so is ideal for applications where aesthetic appearance is vitally important.
- Cure on demand with UV light
- Flowable, low viscosity, thin, wicking, works into thin cracks
- Excellent bondability to Acrylic Plastic
- Excellent bondability to Polycarbonate plastic
- Excellent bondability to PET plastic
- High shear strength
- Fast curing with low-power lamps
- 100% solids, no solvents
- Excellent adhesion to plastics
