Blanket Wash Effective?

Another inquiry was posted from the PNEAC web site. I will forward responses to originator.



This facility is currently using Prisco Auto Wash 6000 for a blanket wash. The product contains 6.48 lbs VOC/gal; vapor pressure is 2.7 mm Hg; flash point is 105 F. The facility uses about 600-700 gal/yr. I have been searching for alternative blanket washes and discovered one possibility in the EPA
Design for Environment Printing Sector project, Cleaner Technologies Substitute Assessment: Lithographic Blanket Washes. The wash is identified only by number, 26. Is anyone familiar
with the product and its performance on both heatset and non-heatset webfed litho

Other possible alternatives that I have encountered are SoyGold which is made by Ag Environmental Products of Lenexa, KS and Prifer 30303+(or The Ink Eater) which is made by Unichema and marketed by Flint ink of Detroit, MI. How well do these products work?

Does anyone have other suggestions for replacing a petroleum distillate blanket wash with a low vapor pressure, less than 30% VOC product?
