Cure wavelength, dose, and matched UV spot system for Permabond UV620.

Permabond UV620's datasheet gives 365–400 nm. Confirm against the manufacturer's current datasheet and validate on your parts. It is covered by SunSpot 2, SkyBeam, SkyWand. Spec match, not a cure guarantee.

What wavelength cures Permabond UV620?

Permabond UV620's datasheet gives 365–400 nm. Confirm against the manufacturer's current datasheet and validate on your parts.

What UV dose cures Permabond UV620?

Permabond UV620's datasheet does not publish a single dose figure; cure it to its 365–400 nm absorption and qualify the exposure with a radiometer at your working distance, then validate on your parts.

Which UV spot system cures Permabond UV620?

All three systems we carry output the 365–400 nm Permabond UV620 needs, so the choice is about your process, not wavelength: the SunSpot 2 for bench and high-dose work, the SkyBeam for an automated line, and the SkyWand for field and rework. This is a spec match, not a cure guarantee, validate on your own parts.

Which Systems Cover It

Wavelength Match

This adhesive cures at 365–400 nm. The dots are our LED wavelengths, the green ones land inside its band.

300350400450500

Our LED wavelengths

365 nm ✓385 nm ✓395 nm ✓405 nm −

3 of our LED wavelengths land inside this band, so an LED system reaches it. The SunSpot 2 arc covers the whole range as well.

SunSpot 2 COVERS

Broadband Arc

Broadband 275–650 nm output spans this adhesive's 365–400 nm absorption at >18 W/cm² UVA.

SkyBeam COVERS

4-Channel LED

Its 365 nm / 385 nm / 395 nm LED channels fall inside this adhesive's 365–400 nm absorption, with per-channel timers and life logs for a logged, repeatable production cure.

SkyWand COVERS

Handheld LED

Its 365 nm handheld LED covers this adhesive for rework, field service, and parts too large for a bench.

Which One to Buy

All three systems output the 365–400 nm this adhesive needs, so choose by how you cure, not by wavelength:

Bench

SunSpot 2

Bench work, and the highest intensity for thick or high-dose cures.

Automated Line

SkyBeam

A fixtured or automated line with logged, per-channel cures.

Field & Rework

SkyWand

Rework, field service, and parts too big for a bench.

Read This Before You Rely on It. These are the manufacturer's published specifications, not our own test results. Whether a cure fully succeeds also depends on your film thickness, joint geometry, substrate, and lamp distance, so always validate the cure on your own parts and process, and confirm the numbers against the manufacturer's current datasheet.
