Beschreibung
Zusammenfassung:	Disclosed herein are pretreatment compositions comprising at least 25 ppm of a phosphonate based on total weight of the pretreatment composition; at least 6 ppm of zinc based on total weight of the pretreatment composition; and a pH of 6.0 or less. Also disclosed herein are systems and methods for treating a substrate with one of the pretreatment compositions disclosed herein. Also disclosed are substrates that have been treated with one of the pretreatment compositions disclosed herein. L'invention divulgue des compositions de prétraitement comprenant au moins 25 ppm d'un phosphonate sur la base du poids total de la composition de prétraitement ; au moins 6 ppm de zinc sur la base du poids total de la composition de prétraitement ; et un pH de 6,0 ou moins. L'invention divulgue également des systèmes et des procédés de traitement d'un substrat avec l'une des compositions de prétraitement divulguées ici. L'invention divulgue également des substrats qui ont été traités avec l'une des compositions de prétraitement divulguées ici.
