Cure wavelength, dose, and matched UV spot system for Dymax 4-20418.

Dymax 4-20418's datasheet gives 385 nm. Confirm against the manufacturer's current datasheet and validate on your parts. It is covered by the SkyBeam LED system. Spec match, not a cure guarantee.

What wavelength cures Dymax 4-20418?

Dymax 4-20418's datasheet gives 385 nm. Confirm against the manufacturer's current datasheet and validate on your parts.

What UV dose cures Dymax 4-20418?

Dymax 4-20418's datasheet does not publish a single dose figure; cure it to its 385 nm absorption and qualify the exposure with a radiometer at your working distance, then validate on your parts.

Which UV spot system cures Dymax 4-20418?

The SkyBeam, whose 385 nm / 395 nm LED channels fall on this adhesive's band. The handheld SkyWand emits only 365 and 405 nm, so it does not reach this wavelength. This is a spec match, not a cure guarantee, validate on your own process.

Our LED wavelengths

365 nm −385 nm ✓395 nm ✓405 nm −

2 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 385 nm absorption at >18 W/cm² UVA.

SkyBeam RECOMMENDED

4-Channel LED

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

SkyWand NOT SUITED

Handheld LED

Neither the 365 nor 405 nm handheld line falls inside this adhesive's 385 nm absorption.

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.
