Publication number: 20020160205Abstract: 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: ApplicationFiled: April 11, 2002Publication date: October 31, 2002Applicant: OMNOVA Solutions Inc.Inventors: Guillermina C. Garcia, Raymond J. Weinert, Martin J. Fay

Patent number: 6465104Abstract: Hotmelt polyurethane adhesive compositions which are solid at room temperature and capable of being cured by moisture are obtained by combining the reaction product of a polyisocyanate and a low molecular weight polymer derived from ethylenically unsaturated monomers and containing active hydrogen groups such as hydroxyl with an isocyanate-containing polyurethane prepolymer derived from one or more polyols. The low molecular weight polymer component may, for example, be obtained by free radical polymerization of mixtures of unsaturated monocarboxylic acids, alkyl esters of unsaturated monocarboxylic acids, and/or hydroxyalkyl esters of unsaturated monocarboxylic acids.Type: GrantFiled: October 23, 2000Date of Patent: October 15, 2002Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Michael Krebs, Yingjie Li, Ingolf Scheffler
