- Resistant to yellowing
- Fast curing with low-power lamps
- 100% solids, no solvents
- Excellent adhesion to metal and glass
PERMABOND® UV620 is a single part, fast curing,
UV curable adhesive. Its excellent optical clarity
and resistance to yellowing make it ideal for
bonding glass and crystal for a high quality
finish. It is well suited for a variety of
applications including glass furniture, decorative
ornaments and other glass objects where high
strength and appearance are required.

*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.
