Definitions

  • the invention relates to a method for simultaneously acting on the top and the underside of a paper carrier web, each with a liquid coating material.
  • Paper is often used as a backing material for adhesive tapes. Find such tapes Use u. a. as masking tapes for painting and varnishing, tapes for processing electronic components or as packaging adhesive tapes.

  • polymers for impregnation are: Styrene-butadiene copolymers, acrylonitrile-butadiene copolymers, acrylates, polychloroprene and polymers of the groups mentioned which have been modified with carboxyl groups or other comonomers. Mixtures of the polymers are also possible, as are mixtures with other substances, for example resins, plasticizers and other auxiliaries.
