I just opened up a 5 gallon drum of dual cure emulsion that I was going to sensitize 1 gallon of, and it has the consistincy of Gak(if you remember that stuff). I was under the impression that if it wasn't sensitized it would keep. My question is, is there anything I can do to bring it back to regular consistancy or is it a lost cause? If it can't use it for imaging could I maybe mix up some and use it as a permanent blockout for stock screens instead of tape. Thanks.
