Had two mishaps with emulsion. One was my fault mistaking a weight vs volume measurement. The other was that my order was mis-shipped. P-mailed Rob, called Terrie, and in 20 minutes Dave Durbin called and we rectified. Dave also clued me into the fact that once the water is added to the diazo it has a rather short shelf life (apparently true for all or most diazos). Did not know that.
Also thanks to Gary at CCI for the explanation. In short, product was overnighted and will be here this am.
Point is that as far back as 20 ys or more this type of response was practically unheard of. Just getting someone on the phone could take days to get back to you. To be sure, social media such as industry forums has had much do with how we all do business in general; both good and sometimes not so much. So thanks to all for stepping up and responding with a sense of urgency. The industry has indeed changed considerably.

You didn't say which product you were referrencing, but I've had Diazo activated WR-25 stay good for 3 or 4 weeks. Much beyond that, no.
Did you mean that you can't mix the Diazo with water and just let it sit... BEFORE stirring it in the emulsion?
-
The second part yes

Yep!
Couple months in the bucket and 2 weeks on a coated screen.
-
To be clear, I am not talking about diazo activated emulsion. Its the diazo powder after the water is added Of course activated emulsion is going to have a long window.
-
Uh Oh... I exceed the two weeks on coated mesh regularly. What will happen if I get stung?
The Nazdar plant in Shawnee (Kansas side of Kansas City) is an amazing place. It's just a couple hours from me.
It gives you a "We Are Serious About INK" feeling--just driving into the parking lot.
I used their ink years ago for screening flatstock, but not in the last decade. No ink, nothing. I probably should rectify that.
-
Stan read closer. Its the bottle of diluted diazo w/ water not the emulsions
-
how long is the shelf-life?
we regularly mix the diazo with water and let it set an hour or so for it to fully break down, shaking a few times in that hour as we go past the screen room.
-
Should be good there.

No no, I got it. But I didn't know it either, until today. I've just been lucky, that I've never done that.
I do do something a little weird, I guess, during our slow times. I divide the gallon BEFORE adding Diazo into 5 equal parts in quart deli cups. Yes, 5. It leaves a little room to cut in the diazo and water mix. Pretty easy.
To divide the diazo, my digital scale is accurate down to a hundredth of a gram (unless the furnace in the ink mixing area is blowing. Then its hopeless.) I divide the diazo into 5 equal parts and put them back into the same bottle that comes with a quart of emulsion. Keeping my emulsion quantities more in line with my needs at the moment, I have only had emulsion go bad once in 7 years.
That won't work in most shops.
I didn't even know Nazdar made emulsion. That's how up to date I am.
-
They don't. Supplier. This product was CCI WR14. BTW extra diazo showed up an hour ago thanx Rob!
-
I need to look at their catalog.
GREAT Customer Service always gets my attention.
-
I regularly have my SP1400 with diazo last 2-3 months without issue in the pot and have used coated screens 6 weeks later without problems. I have had a handful of issues with screens around the 7-8 week mark though, but only when it came to halftones and it just required a longer soak and longer washout than normal, no issues with the final stencil.
-
Go back to top of thread you're not reading close enough
-
The end of October I got 2 gallons of diazo emulsion from NazDar and the "powder" was
hard as a rock. I tried to mix one up because we were in a pinch but no-go. Their "wonderful"
customer service needed the lot numbers from the bad emulsion before they could start the
process of getting us replacements. Two weeks later I was still waiting so I ordered a gallon
from Tubelite which got to us the next day. Still waiting on replacements from NazDar. Not
everybody has the clout Tony does.
-
I'd like to think that's not it.........did you start with your rep? Always the best first step. 800# not so much
-
Tony: thanks for the kind words! Glad Dave got in touch with you and you received the product as needed!
Doug: I am sorry to hear about your situation. Surprises me frankly. Not the lot number part - that is standard procedure to process a return or exchange. I cannot imagine why that part has you upset? Now, the lack of communication beyond that yes - totally empathize with that part.
If you email me (in my sig below) your company name, and the date (approx) of your contact with S1, I will do my best to look into the situation and make it right.
Best, Rob

Nazdar has always been good to us, yes there have been some ups and downs but have always made good on what they said they were going to do. They usually go above and beyond considering we are a small shop. We had two reps in our shop for the better part of the day today.
I will say this much like Tony said dealing with a rep instead of on line is the way to go.
-
Thanks Rob. I will have our purchasing person give you the scoop on what is going on.
-
Rob is showing what customer service is. He saw an issue that he had nothing to do with (as far as I can tell) and decided to step in and at least try to find out what happened and why.
(Of course, he still owes me a beer and I have no explanation from him why I haven't got that yet)
-
Lot of post to the one question I'll ask you Tpep, why would you put water in the diazo bottle anyway if your not going to use right away?

Because they kept sending me fives

I do need to give a thanks and shout out to Rob Coleman with Nazdar. We had a little question pop up while he was at the Long Beach convention. Even though he was probably knee deep in the trade show, he emailed really quick and answered questions. Not that we've had any real problems, more questions to sort out dummy stuff on our end, but Rob and Ginny Gonzolas always get back to us very fast and address the questions. Great personal service!
-
Thanks for the shout-out to my friends down at Evolutionary Screen! Do appreciate it! Fact is, all of you have lots of buying choices - especially toady with this here interweb machine! :) Being a logistics provider as a distributor should be a given -- it's service and knowledge that counts. We (and me) certainly don't do that every time, but it is our goal.
And Dave up there in Cedar Rapids - dang man I do owe ya! I think a run through Iowa may be in order in the coming months. Perhaps I can persuade my fearless leader Mr. Walsh to make a trip with me!
