PREPRIMED METAL SUBSTRATES FOR FORMED METAL APPLICATIONS

摘要

The present invention relates to preprimed metal substrates suitable for use in formed metal applications. The preprimed metal substrate is coated with, as primer layer, (1) a first coating layer applied onto the metal substrate, the first coating layer being based upon a particular hydroxyl group-containing block copolymer, and (2) at least one flexible subsequent coating layer applied onto the first coating layer. The preprimed metal substrates are especially useful in automotive applications.
