Abstract:
1. An aqueous separation liquid for collecting paint overspray from a gas stream comprising: a) at least 49.95 weight percent water, based on the total weight of the aqueous separation liquid; b) at least one non-ionic surfactant; and c) 5 to 50 weight percent based on the total weight of the aqueous separation liquid of an organic water-soluble film-supporting component comprising monomeric polyols having at least three hydroxyl groups in the molecule and polymeric polyols comprising poly(ethylene glycols), polyester polyols, acrylic polyols and polyurethane polyols, whereby components b) and c) are different, the aqueous separation liquid having a viscosity in terms of outflow time in the range of 11s to 25s as measured according to DIN 53 211 using a 4 mm flow cup at 23° C.
