Ulano QX-1 Emulsion is an SBQ sensitized, hybrid dual-cure emulsion that combines the convenience and shelf life of SBQ with the durability, versatility, and imaging properties of dual-cure emulsion.
Ulano QX-1 Emulsion is compatible with all plastisol, UV, and solvent-based ink systems. Its matte finish virtually eliminates printing problems associated with high and low humidity conditions. QX-1 is formulated to provide wide exposure latitude and is easily reclaimed even if underexposed and used with aggressive inks and washup solvents.
Ulano QX-1 Emulsion is durable and has excellent resolution, good definition, and very good wet strength. 37% solids content provides good stencil build per coat, excellent bridging of coarse mesh, and fast-drying capabilities.
Ulano QX-1 Emulsion is presensitized and must be handled in yellow safe light conditions before exposure.Shelf Life - Approximate shelf life for this emulsion is 18 months 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.
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.
