Abstract: Overspray treatment compositions for addition to a water source located within a paint overspray waterwash system located in a spray-paint booth, or a water source that is subsequently applied to such a paint overspray waterwash system for contact with a paint overspray include an amine-functionalized colloidal silica having about 0.1 μmol to 15.00 μmol of amine functionality per square meter of silica surface area, and optionally a coagulant. The compositions and methods described herein work within a pH range of 6.5 and 10 to provide treated paint oversprays. Addition of a flocculant to a treated overspray results in formation of associated complexes having low tack, which may be cleanly separated from the aqueous treatment residue. The aqueous treatment residue may be subjected to one or more additional cycles of use in the paint overspray waterwash system.
