Long-Wavelength UV-Stabilized Plastic Bonding
Low-Viscosity 200-400 cP Application
4-Second Acrylic Fixture

Product Description

Permabond UV632 is a low-viscosity UV-curable adhesive for acrylic and other selected plastics, including many UV-stabilized plastic assemblies. Its long-wavelength photoinitiator cures across 365-420 nm, and viscosity is 200-400 cP at 25 deg C. Typical fixture on acrylic is 4 seconds under a 100 mW/cm2 LED source; actual cure time depends on lamp output, distance and substrate transmission. After cure, overlap shear exceeds 7 N/mm2 on polycarbonate and 4 N/mm2 on PET, with substrate failure in both tests. UV632 can also bond glass and metals when the bondline is accessible to UV light.

Key features

365-420 nm plastic-bonding cure range: The long-wavelength cure range allows bonding through many UV-stabilized plastics.
200-400 cP low viscosity: Low viscosity at 25 deg C supports application to close-fitting plastic assemblies.
4-second acrylic fixture: Typical fixture is 4 seconds on acrylic under a 100 mW/cm2 LED source.

Applications

Bonding acrylic and other selected plastics; bonding UV-stabilized plastic assemblies; glass and metal bonding.
