  • Publication number: 20200306790
    Abstract: Methods and apparatuses for applying coatings on a baggy web are provided. A Mayer rod and a back-up roll engage with each other to form a nip. The back-up roll has a deformable inner layer with a surface thereof covered by a deformable outer layer. The Mayer rod and the flexible web at a contacting area are impressed into the back-up roll with a machine-direction nip width W and a nip engagement depth D, which enables formation of a coating having a substantially uniform thickness.

  • Patent number: 6518360
    Abstract: An essentially solventless process for preparing a hot melt-processable release material comprises the step of providing reactants to a reactor, wherein the reactants comprise at least one backbone polymer having a grafting site that is reactive with a release component to selectively form a release moiety substituent at the grafting site; and a release component that is reactive with the grafting site. The release component is used in an effective amount for imparting release properties to the resulting release material. Also disclosed are release materials preparable thereby and coated substrates comprising the release material. Advantageously, release materials of the present invention are preparable and coatable using a single extruder.
