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.

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.

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.
