Question Wet application of 3M 180-mc. OK, or bad idea?

[chrisinestes]

It'd be super handy to be able to do a wet application of a green color over white in order to get the spacing correct for a white outline. I've used 180-mc, but never wet. Am I asking for trouble, or will it work as well as using 3M/Gerber 220?

Thanks!

You should never use a wet application with an air egress media. The channels trap the liquid. I don’t recall if 180-MC is air egress though.

+1, do not mix wet with airchannels.


With proper registration markers, you will get perfect alignment.

It has micro air channels, and I kinda figured it was a bad idea, but wasn't 100% sure. Thanks!

Why not use 7125? almost all the 180MC colors are available non air release.

Both 7125 and 7725 are cast, 7725 is a little more resilient, and is on a clear liner. I'll use 7725 or Gerber 220, whichever my supplier has.

Thanks!

7125 is the same face stock as 180mc but not air release.

7125 is on a white paper liner. 7725 is the exact same as 7725, just on a plastic liner... It's superior for cutting small text, and good if you're trying to align multiple colors since it's a see through backer... But that's about it, both are cast and use the same adhesive. Not worth the premium if you don't need it.

As others have said... No liquids when using air egress. I'd find the matching Color in the 77xx series and use that if you want wet positionability .

When we do vinyl over vinyl for outlines we just trim the carrier close to the letter, especially around the first and last letters, and along the top and bottom straight letters. Then tape it on and apply with hinge method. Do it day in and day out with no misregistration. This was the normal way to do everything before everything became a wrap.
