Definitions

  • the invention relates to a method for applying liquids, in particular Thermoplastic, on a substrate, whereby the substance is melted, heated and by means of a nozzle or a doctor blade through a perforated cylinder onto a carrier material is applied.
  • the calotte At the end of this transport, depending on the rheology of the fluid, the more or less strongly curved surface above the given base area the calotte.
  • the ratio of the height to the base of the calotte depends on the ratio of the hole diameter the wall thickness of the sieve drum and the physical properties (flow behavior, Surface tension and wetting angle on the substrate) Fluids.
  • the materials must be compatible with the skin, usually air and / or permeable to water vapor, easy to mold and smooth. by virtue of Of these requirements, a carrier that is as thin or soft as possible is often preferred. For handling and use, however, there is also sufficient for the carrier materials Strength and possibly limited elasticity required. Farther should the carrier material have sufficient strength and even after being soaked have low elasticity.
  • adhesives especially preferably self-adhesive compositions used.
  • These preferably belong to the material classes solutions, dispersions, prepolymers and thermoplastic polymers on.
  • Thermoplastic hotmelt adhesives are advantageously used on Based on natural and synthetic rubbers and other synthetic polymers such as examples include acrylates, methacrylates, polyurethanes, polyolefins, polyvinyl derivatives, polyesters or silicones with appropriate additives such as adhesive resins, plasticizers, Stabilizers and other auxiliaries where necessary.
