摘要

A composition for use as a paint detackifying and sedimentation agent is disclosed, which includes 60 to 80% by weight of alumina Al2O3) in pseudoboehmite or boehmite form, either in X-ray amorphous form or with a crystallite size of 20 to 150 A. The composition of the invention may include foam inhibitors, or other conventional additives. A process for use of the composition of the invention is also disclosed in which the composition is added as a 5-30% aqueous dispersion or in dry form to the circulating water of a paint spraying booth and used in a quantity of 1 to 10% by weight, based on 1 kg of the paint to be detackified.
