Patent number: 6436540Abstract: A co-mingled polyurethane-polyvinyl ester composition can be used as a coating, which has good scratch, mar and solvent resistance. The coating is derived from a waterborne polyurethane solution containing free radically polymerizable monomers such as acrylate, ultraviolet light initiators, and optionally urethane crosslinking agents. A process for forming the co-mingled polyurethane-polyvinyl ester composition comprises drying the waterborne polyurethane containing the polymerizable monomers therein and radiation polymerizing, as by ultraviolet light, the free radically polymerizable monomers on a substrate such as a plastic sheet to form a laminate. Subsequently, the laminate can be utilized to form a coating on a product as by thermoforming, where if urethane crosslinking agents are utilized, the polyurethane will be crosslinked.Type: GrantFiled: February 18, 2000Date of Patent: August 20, 2002Assignee: OMNOVA Solutions Inc.Inventors: Guillermina C.

Patent number: 6342280Abstract: The present invention relates to a method for improving both adhesion between substrate and polymer layers and the durability of such composite structures; while maintaining the malleability and preferred characteristics of the original substrate. Quite unexpectedly, the application of a layer or film upon an uncured, encapsulated base substrate which has been encapsulated by the shear thinning methods of the present invention, results in superior adhesion of multiple layers when compared to conventional layering, coating or composite manufacturing methods. Moreover, the uncured or at most, semi-cured, polymer composition applied to the base substrate ensures that the substrate maintains maximum flexibility for subsequent shaping into composite articles prior to curing. The methods described herein produce multiple layer composite articles that are lighter, stronger, more flexible and utilize less material, than composite articles produced by conventional techniques.Type: GrantFiled: June 23, 1998Date of Patent: January 29, 2002Assignee: Nextec Applications, Inc.Inventors: Rodney Lane Patrick, James Michael Caldwell, Peter Uwe Mekailian
