PERMABOND UV640 is a single part, fast setting, and UV curable adhesive designed specifically for bonding plastics. This material has excellent adhesion to a variety of plastics including polycarbonate. Permabond UV640 has very high shear strength, elongation and impact resistance making it ideal for applications that require substrates with different coefficients of thermal expansion.
FEATURES:
- Cure on demand
- High shear strength
- Fast curing with low-power lamps
- 100% solids, no solvents
- Excellent adhesion to plastics
