Description
PERMABOND UV7141 is a UV-curable adhesive with a secondary anaerobic cure mechanism. It can be cured with either UV light or Anaerobic settings.
This makes it ideal for bonding materials such as ceramiccoated glass, mirrors etc. where UV-light cannot penetrate to provide full cure in shadow areas. This dual cure mechanism helps speed up production rates. The UV cure tacks the components in place in seconds, reducing the need for jigging. The bulk of the adhesive then cures more slowly to produce optimum performance.
Features & Benefits
- Cures in shadow areas or in UV light
- Makes for a flexible glue for a variety of repairs or assemblies.
- High shear strength
- Excellent environmental resistance
- 100% solids, no solvents
- Excellent adhesion to metal and glass

*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 lamps peak wavelength with that of the adhesives photoinitiator to ensure optimal adhesive cure.
