The hot-selling Saati Graphic HU42 is one of our most versatile emulsions. It is resistant to UV-cured, plastisol, solvent-based, and water-based inks. The controlled particle size results in excellent print definition on any mesh. Upon drying, it lacks the tackiness typical of dual-cure emulsions. Graphic HU42 appears blue/green. When sealed in the original container and stored in cool conditions, SaatiChem products will maintain their original properties for one year from the date of production. Diazo is included in packaging.

Shelf Life - Approximate shelf life for this emulsion is 24 month (2 years) when stored at room temperature. It should not be stored at temperatures above 80f (27c) or below 37f (0c). For best results it should only be stored in its original container.
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.
