902 QDC dual cure emulsion.
902 QDC Dual Cure Emulsion is recommended for plastisol and can be used with all ink systems. Reclaiming the cured film is easy; the screen may be reclaimed with our stripper. Diazo is added by first adding room temperature water, shaking properly until dissolved, and then adding the solution to the emulsion. Mix well into the emulsion and let stand for at least 30 minutes to release any air bubbles that may have been formed.
Preparation of Screen & Emulsion:Clean the screen with a degreaser and let it dry completely. add water to the diazo bottle & shake for a minute or so making sure that all of the diazo is dissolved you may apply one coat of emulsion with diazo on the squeegee side and one on the print side or two coats on each side starting from the print side. the more coats you put on heavier the stencil will be achieved. with a heavier stencil, the exposure time will be increased. let the emulsion film dry and then wash the screen with a mist of water to open the image area.. get all the water out by air or by blotting otherwise the residue of the emulsion may run into the image area, blocking the ink. look for any pinholes. 902qdc does not usually yield any pinholes if exposed within the optimum exposure limits. if there are pinholes use block-out to close the pinholes.
- The broad spectrum of exposure limits, longer latitude
- Excellent resolution
- High edge definition
- Perfect mesh bridging
- Fast drying
- Longer print capabilities with great durability
- Easy reclaiming
- Excellent humidity resistance
- Quicker exposure
- Best choice for developing half tones and fine lines

Distance for the exposure should be about one and a half times the diagonal measurement of the artwork from point light sources. Yellow & orange mesh requires at least 50% more time than white mesh. The times given below are based on white 110 White mesh approximately 40 inches.
