<p>A chemical composition for stripping and cleaning surfaces of grease, paint and the like. The chemical composition comprising a synthetic water absorbant and swellable polymeric substance for absorbing a solution of a stripping and cleaning agent. The synthetic polymeric substance may be a product marketed in Australia under the trade mark "AGROSOKE", a crosslinked acrylamide or methacrylamide polymer, a crosslinked acrylamide or methacrylamide polymer and a copolymer of acrylamide and acrylic acid, or a crosslinked copolymer of acrylamide or methacrylamide and acrylic acid or methacrylic acid. The stripping and cleaning agent is an aqueous solution of a caustic alkali such as sodium hydroxide which may be optionally enhanced by adding components such as ammonium compounds, compounds containing amine groups and organic solvents at the appropriate time depending upon the intented application.</p> |
