KIWO HARDENER K

HARDENER K is a red-colored chemical hardener that is applied to the stencil screen after developing the image to increase the water resistance of most photo emulsions. It works especially well with KIWOCOL POLY-PLUS HWR emulsion. HARDENER K chemically crosslinks with the emulsion for maximum resistance and will often result in an un-reclaimable permanent stencil. Depending on the chemical structure of the emulsion, an absolute water proof stencil may be achieved that is no longer reclaimable.
