Ulano 925WR-P Diazo Emulsion
The Ulano 925WR-P is a water-resistant Diazo emulsion that shares the main characteristics of Ulano's TZ emulsions, but with a higher solids content and similar resolution, edge definition and exposure latitude. Stencils produced with 925WR-P are completely water resistant and very durable.
Ulano 925WR-P is Phthalate-free and comes with a powder diazo sensitizer for faster and surer mixing. This emulsion is an excellent choice for imprinted sportswear.

Emulsion Exposure Differences
Proper screen exposure must take many factors into account – the emulsion type, coating thickness, exposure unit, etc. As a general guideline for the different emulsion types (diazo, dual cure, and photopolymer) use these times as a reference.
Photopolymer – These are typically the fastest exposing emulsions, with many exposing correctly from 30-50 seconds. The shortest times can be seen when using a newer LED-type exposure unit.
Dual Cure – If you have established a good exposure time with photopolymer emulsions, you can typically add 90 seconds (1.5 minutes) to that time for most dual cure emulsions.
Diazo - If you have established a good exposure time with photopolymer emulsions, you can typically add 210 seconds (3.5 minutes) to that time for most diazo emulsions.These times will depend heavily on your exposure unit and should only be considered as a starting point.
