Abstract
Abstract Compositions for cleaning and priming a surface comprising a solution of titanium acetylacetonate; alkanol having 1 to 4 carbon atoms; alkanol selected from methylethylkeytone, methylisobutylketone, acetone and their mixture; and water. The compositions, which perform both cleaning and priming in a one-step operation, cure quickly allowing rapid painting.
