SELF-STRIPPING COATING COMPOSITION

摘要

An improved stable self-stripping aqueous coating composition, adapted to simultaneously disperse a previously desposited dried coating composition and replace the dried composition with a fresh coat, includes a solution of a alkali soluble resin of low molecular weight and high acid number and aqueous ammonia in sufficient concentration to provide a pH no less than about 9.0. Surfactants and waxes may also be employed in the coating composition as well as conventional additives, however, metal-fugitive ligand complexes are not needed for the self-stripping properties.
