Completely exposed water resistant stencils for discharge textile, and ceramic inks should not need an extra hardener if they are completely exposed. Complete exposure means all the stensitizer has been crosslinked with the emulsion achieving all the water resistance it was designed to have.
Ulano stencil hardeners penetrate the stencil and form an additional chemical bond with the mesh that stencil removers cannot break. This means you should not expect to reclaim your mesh after applying a hardener. Under exposed stencils are effected even more than properly exposed stencils.
Hardener D is a liquid stencil hardener formulated for use with QT-DISCHARGE direct emulsion to improve its durability and water resistance. Hardener D can be used with other textile emulsions but will make stencil removal more difficult and may embrittle the stencil.
- Improves the durability and water resistance of QT-DISCHARGE emulsion
- Can be used with other textile emulsions
Three modes of drying /curing possible
- Dry and use in 1 hour or less
- Dry for 24 hours at room temperature
- Heat cure
Occupationally and environmentally friendly
- Virtually odorless
- Classified VOC-free
- 1 year 68° F. (20° C.)
Hardener D is available in quart (946 cc.), U.S. gallon (3.78 lt.), 5 U.S. gallon (18.9 lt.), and 50 U.S. gallon (189.2 lt.) units. Quart units are packaged 12 per carton; U.S. gallon units are packaged 4 per carton; 5 and 50 U.S. gallon units are packaged individually.
As a companion product to QLT(when it is used with added diazo to provide
resistance), we’ve introduced Hardener WR to improve QLT’s durability and water
resistance. It can also be used with most diazo sensitized, diazo-dual cure (water
resistant) emulsions, and SBQ textile emulsions to which diazo has been added.
Whereas virtually all hardener treatments make stencils permanent, stencils treated
with Hardener WR can be removed easily!
Hardener X is a post-exposure and processing, liquid screen stencil hardener which improves the stencil durability of textile direct emulsions, including 925WR, TZ, LX-630, LX-660 AND QTX®. For industrial use only.
You should not expect to reclaim your mesh after applying a hardener. Hardeners penetrate the stencil and form an additional chemical bond with the mesh that stencil removers cannot break. Ulano hardeners can be used with other textile emulsions, but will make stencil removal more difficult and may embrittle the stencil.
- QHARDENER X 1 quart (0.946 liters) 12 per case

- 5GHARDENER X 5 gallons (18.927 liters) -Ships Hazardous
- 50GHARDENER X 50 gallons (189.25 liters) -Ships Hazardous
Hardener X is applied to both sides of the screen with a soft bristled brush or sponge after the stencil has been properly exposed, washed out and thoroughly dried. Blot excess solution from the image area.
Allow the screen to cure for 24 hours at room temperature. To accelerate the curing process, the screen can be exposed to heat, not exceeding 140 degrees Fahrenheit (60 degrees centigrade), for one hour.HEALTH AND SAFETY INFORMATION
Hardener X is for industrial use only and should be used only in well ventilated areas. Avoid contact with the skin, eyes, mucous membranes, and clothing. Hardener X may be harmful if swallowed. Wear rubber gloves and eye goggles. Avoid contact with the skin. Wash hands promptly after use.
CALL A PHYSICIAN AT ONCE.
Eye Flush immediately with water for at least 20 minutes. External-flush exposed areas with water for 15 minutes.
Internal Rinse mouth with bicarbonate of soda and drink large quantities of water. Do not induce vomiting.
