A METHOD FOR PREVENTING DELAMINATION OF POLYMERIC COATINGS FROM A METAL SUBSTRATE

摘要

The present disclosure provides a method for enhancing resistance to delamination of a coating layer applied to a rigid, monolithic substrate (204, 404). The method comprises forming a plurality of holes (208, 408) on the substrate (204, 404), to define passages from a first operative surface to a second operative surface of the substrate (204, 404). The first operative surface is coated with a first coating material and the second operative surface is coated with a second coating material, to obtain a first operative surface having a first coating layer (202, 402), and a second operative surface having a second coating layer (206, 406). A portion of the first coating material and/or the second coating material is allowed to flow through the passages to configure contiguous ties (210, 410) between the first and the second coating layer. The contiguous ties formed between the first and the second coating layer aid in enhancing the resistance to delamination of the coating layer applied to the rigid, monolithic substrate (204, 404).
