Zusammenfassung:The composition includes a polysiloxane having at least one of a phosphate or phosphonate group and an amino-functional compound having at least one silane group. The method includes treating the metal surface with a composition including a polysiloxane functionalized with at least one of a phosphate or phosphonate group. The method can include first treating the metal surface with a primer composition including an amino-functional compound having at least one silane group or including an amino-functional compound having at least one silane group in the composition with the polysiloxane. Certain polysiloxanes functionalized with at least one of a phosphate or phosphonate group are also described.
