Cure wavelength, dose, and matched UV spot system for 3M LC-1211.

3M LC-1211's datasheet gives 400–500 nm. Confirm against the manufacturer's current datasheet and validate on your parts. It is covered by the SunSpot 2. Spec match, not a cure guarantee.

What wavelength cures 3M LC-1211?

3M LC-1211's datasheet gives 400–500 nm. Confirm against the manufacturer's current datasheet and validate on your parts.

What UV dose cures 3M LC-1211?

3M LC-1211's datasheet does not publish a single dose figure; cure it to its 400–500 nm absorption and qualify the exposure with a radiometer at your working distance, then validate on your parts.

Curing 3M LC-1211 With a UV Spot System

Q: Which UV spot system cures 3M LC-1211?

The SunSpot 2. Broadband 275–650 nm output spans this adhesive's 400–500 nm absorption, including the visible-light content this adhesive uses to cure in depth. This is a spec match, not a cure guarantee, validate on your own process.

3M LC-1211 is a visible-light-cure acrylate. Its manufacturer's datasheet cures it at 400–500 nm. 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 400–500 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 RECOMMENDED

Broadband Arc

Broadband 275–650 nm output spans this adhesive's 400–500 nm absorption, including the visible-light content this adhesive uses to cure in depth.

SkyBeam NOT SUITED

4-Channel LED

LED output at 365–405 nm can't supply the visible-light content this datasheet calls for, so use the broadband SunSpot 2.

SkyWand NOT SUITED

Handheld LED

The handheld LED can't supply the visible-light content this adhesive needs.

Worth Knowing: A visible-light-cure adhesive (400-500 nm); only the broadband SunSpot 2 delivers that full visible range. An LED head reaches only the low 405 nm edge.

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.
