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

*The cure time depends on the power of the UV lamp, its spectral output, the distance between the lamp and the components, and the transmission characteristics of the substrates.
**LED UV lamps have a narrow range of spectral output. It is important to check suitability with Permabond in order to match the LED lamp’s peak wavelength with that of the adhesive’s photoinitiator to ensure optimal adhesive cure.
