Abstract

Novel scale and corrosion inhibiting composition for protecting metal surfaces in contact with water. The composition is characterized by comprising a film-forming amine component, an alkalized amine component and an organic polysulfonic component whose molecule comprises at least two units of the structure (Io) in which A is a hydrogen atom or a C1-C4 alkyl group and X is a hydrogen atom, a Na<+>, K<+> or NH4<+> cation or a C1-C4 alkyl group. The invention also provides a method for the preparation of said composition.
