    摘要: A process for the coating of surfaces of a metallic component to be formed by contacting the surfaces of the metallic component prior to forming operation with an aqueous composition containing 80% by weight of at least one organic film-forming ionomeric polymer or copolymer, whereby the total organic polymeric material has an average acid number in the range from 20 to 300, optionally at least one further organic film-forming polymer different from the organic film-forming ionomeric polymer or copolymer; optionally a neutralizing agent; a low temperature corrosion inhibiting cross-linking agent and water. The pH of the aqueous composition at the beginning of the coating process is in the range from 6 to 10.5.
