  • Publication number: 20200393780
    Abstract: An intermediate transfer member, and a method of producing a seamless intermediate transfer member blanket for the intermediate transfer member are described. The method comprises applying a release formulation to an endless belt intermediate transfer member blanket precursor by contacting an applicator roller with an outer surface of the intermediate transfer member blanket precursor; curing the release formulation to form a release layer; applying a fluoropolymer membrane to a portion of the release layer; disengaging the applicator roller when the applicator roller is in contact with the fluoropolymer membrane, such that the fluoropolymer membrane is at least partially coated with the release formulation; and removing the fluoropolymer membrane from the surface of the release layer to form the seamless intermediate transfer member blanket.

  • Publication number: 20180039207
    Abstract: Herein is disclosed a method of coating a web with a release formulation. The method comprising: providing a coating station comprising a rotatable applicator roller to apply a release formulation coating to a web; applying a release formulation coating to a surface of the applicator roller, the release formulation comprising at least one silicone oil; feeding the web through the coating station such that the web engages with the applicator roller; and applying the release formulation coating to the web under a shearing force by rotating the applicator roller such that, at a location at which the web and the applicator roller engage, the surface of the applicator roller moves in the opposite direction to the direction the web is fed through the coating station.
