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