Coating line and process for forming a multilayer composite coating on a substrate |
摘要 |
A process for forming a multilayer composite coating on a substrate is provided. The process includes forming an electrodeposition coating layer on the substrate by electrodeposition of a curable electrodepositable coating composition over at least a portion of the substrate. Optionally, the coated substrate is heated to a temperature and for a time sufficient to cure the electrodeposition coating layer. A basecoating layer is formed on the electrodeposition coating layer by depositing an aqueous curable basecoating composition directly onto at least a portion of the electrodeposition coating layer. Optionally, the basecoating layer is dehydrated. A top coating layer is formed on the basecoating layer by depositing a curable top coating composition which is substantially pigment-free directly onto at least a portion of the basecoating layer. The top coating layer, the basecoating layer, and, optionally, the electrodeposition coating layer are cured simultaneously.
