摘要: The invention relates to water-swellable hot-melt-type adhesives based on a tackifying resin, water-dispersible EVA wax, an ethylene acrylic-acid ester copolymer, water-soluble homopolymer or and superabsorber polymer powder with average particle size of less than 80 νm. inventive adhesive comprises noticeably improved swelling behavior compared that the prior art. In addition, agent is distributed in matrix essentially homogeneous manner. Hot-melt-type this type are suited for ensuring longitudinal water tightness modern cable constructions, as joint sealing materials used construction industry protection reconstruction buildings. also producing absorbent textile area hygiene.
