TZ Ulano's blue TZ emulsions are formulated for use with water-based inks, water dyes and plastisols. TZ produces stencils with excellent mechanical resistance, good resolution and edge definition, and excellent water resistance. Stencils are easy to reclaim. Recommended for imprinted sportswear applications.
Ulano TZ/CL is the same as TZ, but supplied clear for easier see-through registration. (Separate blue color supplied with purchase.)
TZ/HY-200B Higher viscosity for better coating control with very coarse mesh.
Emulsion Exposure DifferencesProper 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.
