Title:

METHOD OF PRODUCING DURABLE LAYERED COATINGS

Document Type and Number:

WIPO Patent Application WO2000041530

Kind Code:

A3

Abstract:

The present invention relates to a process for producing a durable multi-layered coating on difficult-to-coat substrates, such as aluminum. The process includes subjecting the surface of the difficult-to-coat substrate to an adhesion promoting step, followed by applying an intermediate layer of flexible primer, which contains a polyester copolymer produced through a two-stage polymerization process. A mar resistant top layer of clear coating composition is then applied over the intermediate layer to produce the multi-layered durable coating on the difficult-to-coat substrate. If desired, the intermediate layer may be pigmented or it may be applied in the form of one or more patterned layers of different colors. Alternatively, one or more patterned layers of different colors may be applied over the intermediate layer before the application of the mar resistant top layer. If desired, the application of the mar resistant top layer and the patterned layers may be delayed by up to 12 weeks to permit the user to mass produce coated components, such as delivery van bodies, with an intermediate layer in a basic color, such as white, which can be then custom coated with various design patterns, followed by the application of the mar resistant top layer.
