Description
PERMABOND UV670 is a single part, fast curing, UV curable adhesive. The cured adhesive is tough, flexible and has excellent impact resistance. Permabond UV670 is well suited for bonding glass to metals and metalized plastics.
It is a medium viscosity, moderatly flowing UV glue
- Cure on demand
- Flexible, good impact resistance
- Fast curing with low-power lamps
- 100% solids, no solvents
- Excellent adhesion to metal and glass
