We are
using the HM531 Type 4 for one specific application.
We
like it so much we will be looking into their Type 3.

Hi All!
Well, after a week of
getting the bejeebers scared out of me listening to tornado warnings and
watches being broadcast, sirens going off (Friday night), we've got a
beautiful day here. Luckily, we didn't catch much of the really bad storms
here in Tulsa...
Anyway, I've just been recently informed that the R560
(water soluble), and the R244NC (no-clean) is coming off Kesters "Preferred"
products. They're being replaced by a HM531 (water soluble), and a PM202
(no-clean).
I'm getting samples sent to me of course, to do my own
evaluations, but I was just wondering if anybody else has switched over to the
new formulas, and how they like them.
From a couple of discussions I
have had with Kester, and reading the datasheets, these new pastes will print
at faster squeegee speeds (which isn't a big deal to us since we're a
low-to-medium volume shop), and wets better to different finishes, such as
Ag/Pd and OSP's.
The one thing that I did notice with the HM531 that I
don't care for a whole lot, is that the shelf life has decreased to 4-months
vs. 6-months with the R560. I can envision now, since we buy our paste through
distribution, that we're going to get paste that will have very little shelf
life left. We were running into that problem occasionally even with 6-month
life paste.
