XENON 902QDC Emulsion is a fast-drying Dual Cure photo emulsion. 902QDC is resistant to both solvent and water and can be used with all ink systems. Diazo is added in the normal way by first adding room temperature water, agitating before adding the solution to the emulsion, then allowing the emulsion to stand for at least 30 minutes to assure any air bubbles introduced during mixing are released. Reclaiming 902QDC is easy with Xenon Stencil Remover, which is available in paste and liquid form. Diazo Sensitizer is included in the package.
