  • Publication number: 20080138627
    Abstract: A multi-component composite coating composition comprising an aqueous-based film-forming composition serving as a color coat or a basecoat and a polyepoxide-polyacid clearcoat is disclosed. The polyacid is made from ring opening a polybasic anhydride with a polyester polyol formed from reacting a polyol with a polycarboxylic acid having at least 20 contiguous carbon atoms between the carboxylic acid groups.

  • Patent number: 7329468
    Abstract: The present invention provides an improved multi-layer composite of two or more polymeric layers at least one of which is formed from a thermosetting composition. The composite includes at least a first polymeric layer formed on a substrate and a second polymeric layer over the first polymeric layer, wherein in the absence of a boron-containing compound, the first and second polymeric layers have poor interlayer adhesion. The improvement resides in the inclusion of at least one boron-containing compound in one or both of the first and second polymeric layers in an amount sufficient to improve the interlayer adhesion between the first and second polymeric layers. Also provided is an improved curable coating composition used to form a multi-layer composite coating of two or more cured coating layers, at least one of which is formed from the thermosetting composition. Related methods and coated substrates are also provided.

  • Publication number: 20070278104
    Abstract: 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.
