DZ 343
Chromaline DZ 343 is a violet diazo cure photo-emulsion for water-based and plastisol inks. DZ 343 can withstand thousands of prints without the use of chemical hardeners and still reclaim easily. At 48% solids, 200+ micron stencils are easily achieved. DZ 343's combination of faster exposure speeds, medium viscosity, and high durability gives printers even greater versatility and value. Freeze/thaw stable.
*Sensitizer included

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.
