ProChem® WR-12 is a high viscosity Diazo photo-emulsion recommended for Plastisol and Water-based inks. ProChem®WR-12 has a very high solid content (43%) and has excellent water resistance. Mix Diazo as per instructions before adding the solution to the emulsion. Allow the emulsion to stand for at least 2 hours to assure any air bubbles introduced during mixing are released. ProChem® WR-12 is easy to reclaim with CCI Stencil Removers which are available in concentrate and ready-to-use formulas.
