Abstract:
A surface conditioning composition for use in surface conditioning of a metal prior to being subjected to a phosphate-based chemical conversion treatment, in which the surface conditioning composition has a pH of 3 to 12, and includes at least one kind of zinc compound particles selected from the group consisting of zinc oxide particles, zinc hydroxide particles, and basic zinc carbonate particles; phosphoric acid and/or condensed phosphoric acid; and an amine compound having a specific structure and in which the zinc compound particles are dispersed and stabilized by the phosphoric acid and/or condensed phosphoric acid, and the amine compound.
