Patent number: 11767447Abstract: Provided herein is a topcoat composition comprising at least one fluorosilicone, a hydride-functional crosslinking agent, an infrared-absorbing filler, and at least one dispersant that is non-reactive with the hydride-functional crosslinking agent, by weight based on a total weight of the topcoat composition, wherein the topcoat composition has a degree of crosslinking between about 10 micrograms/hour/milligrams to about 20 micrograms/hour/milligrams. Further provided herein are methods of making the topcoat composition, as well as an imaging blanket and methods of reducing coating defects on a media coated using the imaging member.Type: GrantFiled: January 19, 2021Date of Patent: September 26, 2023Assignee: XEROX CORPORATIONInventors: Kenny-Tuan T. Dinh, Alexander N. Klymachyov, Lin Ma, Kyle B. Tallman, Eric Robert Dudek, Michael L. Mehan, Harry F. Freitas, Jr., Angela Schnuerch, Michael S. Roetker, Ngoc-Tram Le, Varun Sambhy, Santokh S.

Publication number: 20220380592Abstract: Compositions include polymer filaments compatible with fused filament fabrication, comprising: a thermoplastic polymer; and a bio-based additive admixed with the thermoplastic polymer in an effective amount to decrease total volatile organic compound (TVOC) emissions under additive manufacturing conditions, as determined by gas chromatography and measured relative to the thermoplastic polymer alone, by at least about 10% on a weight basis. Methods for forming a polymer filament compatible with fused filament fabrication may comprise: forming a melt blend comprising a thermoplastic polymer and a bio-based additive; and extruding the melt blend and cooling to form a polymer filament comprising the bio-based additive admixed with the thermoplastic polymer.Type: ApplicationFiled: June 1, 2021Publication date: December 1, 2022Applicant: Xerox CorporationInventors: Judith VANDEWINCKEL, Mark MERCANDETTI, Angela SCHNUERCH, James WINTERS

Publication number: 20220049123Abstract: Provided herein is a topcoat composition comprising at least one fluorosilicone, at least one infrared-absorbing filler, and silicone dioxide present in an amount ranging from greater than about 5% to about 10%, by weight based on a total weight of the topcoat composition, wherein when the topcoat composition has a shear rate between about 2 s?1 to about 3 s?1, the topcoat composition has a viscosity ranging from about 1500 mPa/s to about 500 mPa/s and the shear rate does not decrease as the viscosity increases or decreases. Further provided herein are methods of making the topcoat composition, as well as an imaging blanket and methods of reducing coating defects on a media coated using the imaging member.Type: ApplicationFiled: August 12, 2020Publication date: February 17, 2022Applicant: XEROX CORPORATIONInventors: Kenny-Tuan T.
