Ulano Proclaim Dual Cure Emulsion
Ulano Proclaim is a diazo-photopolymer (dual-cure) emulsion formulated to provide unequalled exposure latitude and ease of decoating, even if underexposed and used with aggressive inks and solvents. Proclaim is fast-exposing, and provides good acutance.
Its high solids content (37%) provides good stencil build per coat, excellent mesh bridging, and fast-drying capabilities. Proclaim has superb coating properties and durability, and is resistant to all solvent-based inks as well as water-based UV-cured inks. Proclaim is ideal for general graphics, textile, and industrial applications.
Light blue in color, Proclaim turns light green when sensitized. Properly exposed non-image areas revert back to the original blue color, providing a built-in indicator of adequate exposure. Packages included sensitizer.
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.
