Abstract:
This invention relates to a method for phosphating metal surfaces in which the metal surfaces are treated with an aqueous phosphate and titanium-based colloidal activating agent prior to phoshating, wherein the activating agent comprises at least one water-soluble silicon compound having at least one organic group. The invention also relates to a corresponding activating agent.
