ABSTRACT:
The composition of a non-chrome post-rinse composition for treating phosphated metal substrates is disclosed. The composition comprises the reaction product of an epoxy-functional material containing at least two epoxy groups; and an alkanolamine, or a mixture of alkanolamines. The composition further comprises a group IV-B metal ion, or a mixture of group IV-B metal ions. Also provided is a non-chrome post-rinse concentrate; a process for treating a phosphated metal substrate comprising contacting said phosphated metal substrate with the non-chrome post-rinse composition described above; and the coated article prepared by this process.
