The key to drying is that all the water contained in the emulsion must be completely evacuated from the coating. This is generally accomplished by using heat, a dehumidifier, or both. A typical coated screen generally will be dry to the touch after one hour at 70°F (21°C) and relative humidity of 50%.
Subsequently, How long does it take for diazo emulsion to dry?

How long can I leave emulsion on a screen?
Any emulsion that has diazo added (Dual Cures, Diazo, and hybrid emulsions) as a sensitizer will last about 4 weeks of optimum sensitivity as long as storage conditions are light safe and below 80F degrees. A pure photopolymer emulsion coated screen can last up to 6 months and is unaffected by heat.

How many times can you reuse a silk screen?
You can reuse a screen thousands of times, but you have to know how to properly clean and reclaim them. Being too rough with your screens can lower their lifespans, but not cleaning them thoroughly can result in poor emulsion adhesion, pinholes and blurred prints.

How do you clean silk screen after use?
I use Diazo Emulsion Remover to dissolve the photo emulsion from the screen. I take a paint brush and coat one side with the remover and then flip the screen over and coat the other side as well. Allow the emulsion remover to soak in exactly 1.5 minutes and then scrub with a nylon brush or scrubber.
How do you know if emulsion is bad?
If the emulsion doesn’t perform like it used to and you increase your times and still can’t get a good burn, then most likely it’s bad. You can place the emulsion in a refrigerator to make it last longer.
