Typical Curing Properties

Typical fixture time (acrylic)*

Low power 4mW/cm² battery lamp: 10secs

LED 100mW/cm² lamp: 4 secs

UV light guide 30W/cm²: 2 secs

Cure wavelength 365 – 420 nm**

*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 to match the LED lamp’s peak wavelength with that of the adhesive’s photoinitiator to ensure optimal adhesive cure.
