CCI Harden X Emulsion Hardener - Gallon
ProChem HardenX is a one part chemical hardener designed to increase the water resistance of photo-emulsions. ProChem HardenX increases the print durability and reduces premature stencil breakdown. It is excellent for high humidity conditions. With some emulsions, Harden X may produce a waterproof stencil that is difficult to reclaim without the use of a hardener remover.
