400 plus micron stencil

[alan802]

Yea, I coated up a 83/100 screen this afternoon 1/7 coats and got over a 400 micron stencil...yea I know it's not that important but you asked 

Watcha gonna do with that stencil?

I've got a newman 102N with a 200 micron eom stencil waiting in the dark room for something special.  That ought to cover just about any one hit white scenario I can think of, even on black 50/50.

Got a little HD project this morning.  Ya know the thing that is hardest about these super thick stencils is getting them to dry fast enough without dripping but also smooth as in not too fast air movement.  I'm trying my best to avoid cap film.

How's that PHW red for quick drying?  Nice build up?

I think it's a 102 Newman mesh

The PHW is the best emulsion I've found for building thick stencils.  I haven't put a stopwatch on the drying times and we haven't had to coat a screen and turn it around quickly so I couldn't tell you with any certainty whether it's quick drying or not.  I think the fastest we've turned one around was coating one at the end of the day and using it the next morning.  I really like this emulsion and even with very thick stencils, you can see through it to line up jobs on press or using the mhm style film positioning unit to line up films.  I don't see us using anything different than the PHW for our thick stencils, I'm very happy with it.

102 Newtons?

Like Dave said, it's a 102 Newman Roller Mesh, stretched to 48 newtons.

I've heard of coating a screen, drying, then building a damn out of tape or what have you on
the substrate side, then pouring in emulsion. Never tried it, sounds feasible. Difficult to gauge
thickness though.

Wouldn't thicker cap film be easier and faster? I know some people will build up layers of cap film too.

Ever seen the price of 800 micron film? Yikes!

I can get a 400 micron film fast and easy using PHW Red. I haven't tried to get much thicker, as I don't need it ....yet. Coat them end of the day and ready to go in the AM. We can run thousands of pieces with this stencil.

How many coats does it take you to get the 400 microns?

What is PHW? Who makes it.

[squeegee]

It's Saati.  I was checking with Ulano yesterday and they have QT Thix for thick stencils, 52% solids, anyone tried it?

[alan802]

I've never had any Ulano emulsion in production, I've tried samples over the years but nothing I really liked enough to put into use full time.  One of the emulsions that I really liked was around $100/gallon so you can see why I never pulled the trigger on that.

C'mon Alan, no one is cheaper than yours truly, but if there was an emulsion at that price that I found made better prints, or sped production time, even I would be on it in a heartbeat.
I've gone though plenty of $90 emulsion over the years.
