Agents for unsticking paint, and sedimentation agents

A composition suitable as a paint detackifier and/or sedimentation agent comprising:

• (a) one or more aluminum compounds comprising amorphous alumina, pseudoboehmite alumina, boehmite alumina, hydrates of said aluminas, and mixtures thereof wherein said pseudoboehmite and boehmite aluminas have an average crystallite size of from 0.1 to 15 nm, measured by X-ray defraction on the 021 reflex;
• and
• (b) at least one hydroxyalkyl polysaccharide having 0.5 to 6 hydroxyalkyl groups per ring unit on the average, wherein the hydroxyalkyl groups, independently of one another, have 2 to 6 carbon atoms, with a weight ratio ranging from 100:2 to 100:20, based on the ratio of total alumina, calculated as Al2O3, to hydroxyalkyl polysaccharide.
