Ulano 925 WR emulsion
« on: December 05, 2011, 10:36:33 PM »
Any thoughts on this emulsion? 1 particular question, how much syrup is supposed to actually be in the sensitizer bottle? I have a guy selling a gallon for real cheap unopened but the sensitizer bottle is the syrup kind and there is not much in there at all. Is that how its supposed to be?

I can't tell you exactly how much sensitizer is supposed to be in there, but can assure you that the bottle is pretty empty, to allow water to be added and the powder or syrup to be dissolved when shaken,

It's all i use.

Use warm water and fill the bottle 1/2 way. Stir the syrup first then add the rest of the water and shake well.

I've used enough of that emulsion to fill an olympic pool.

What I like:
VERY water resistant with no post hardening required
Easy to mix with the syrup
Good shelf life

Trade-off:
Not as high resolution as some other diazo emulsions


Do you have specific questions about it?

Do you think it is possible to split up the gallon into 4 qts?

With powdered sensitizer, it's much easier to divide it into four for quarts than with syrup. I don't know if diluting it with water, to make it easier to divide will affect it's life, but you may be able to extend it with refrigeration, (similar to sensitized emulsion).

Otherwise, they only rate sensitized emulsion at 3-6 weeks, but up to three months in a fridge. Here's the Tech Sheet. http://www.ulano.com/TechData/925-925WR.tds.pdf

Looks like ill have to make room in the fridge! lol. I know you can way the powder on a gram scale and that is what I thought about the syrup but you would have to add the water. Now does anyone know if the clock starts on the sensitizer as soon as water is added.

Probably starts when diluted, but I'd call a tech at Ulano if I were you. Those guys usually love their work and are happy to help.

good stuff. We use if for the occasional water based project, works great. Usually a little harder to reclaim, but no deal breaker. We buy it by the quart and keep it in the fridge.
