Cure wavelength, dose, and matched UV spot system for Loctite 4305.

Loctite 4305's datasheet gives 365 nm, at 30 mW/cm² at 365 nm for 10 s. 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 Loctite 4305?

Loctite 4305's datasheet gives 365 nm, at 30 mW/cm² at 365 nm for 10 s. Confirm against the manufacturer's current datasheet and validate on your parts.

What UV dose cures Loctite 4305?

Loctite 4305's manufacturer datasheet (Henkel LOCTITE 4305 Flashcure Technical Data Sheet) publishes 30 mW/cm² at 365 nm for 10 s. UV dose = intensity × time, so at a measured intensity you solve exposure time from the target dose. Verify with a radiometer at your working distance and validate on your parts.

Which UV spot system cures Loctite 4305?

All three systems we carry output the 365 nm Loctite 4305 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.

Curing Loctite 4305 With a UV Spot System

Loctite 4305 is a UV/visible-cure cyanoacrylate (Flashcure). Its manufacturer's datasheet cures it at 365 nm, 30 mW/cm² at 365 nm for 10 s. Here is which Uvitron UV spot systems cover that wavelength, how to choose between them, and what to confirm before you run production.

Which Systems Cover It

Wavelength Match

This adhesive cures at 365 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 −

1 of our LED wavelength 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 nm absorption at >18 W/cm² UVA, with the intensity headroom to reach a 30 mW/cm² at 365 nm for 10 s dose quickly.

SkyBeam COVERS

4-Channel LED

Its 365 nm LED channel falls inside this adhesive's 365 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 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.

Cure Recipe Calculator

Loctite 4305's datasheet implies about 300 mJ/cm² (30 mW/cm² for 10 s). Measure the intensity your system delivers at the working distance with a radiometer, and this gives the exposure time for that dose, since dose = intensity × time.

Your measured intensity
mW/cm²

Estimate only. Cure also depends on film thickness, geometry, substrate, and inhibition, so qualify the result on your own parts.

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.
