PERMABOND® UV6361 is a UV-curing adhesive developed for use on plastics. It has good adhesion to PET 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. UV6361 cures to give a colourless bond so is ideal for applications where aesthetic appearance is vitally important.
FEATURES:
- Cure on demand
- Ideal for bonding PET and recycled PET
- 100% solids, no solvents
