*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.
*NO RETURNS ON UV GLUE.
