Danquinsa DANCOLL® W155 PU dispersion
Categories: Polymer; Thermoplastic; Polyurethane, TP

Material Notes: DANCOLL_W155 is an aqueous, soft aliphatic polyurethane dispersion with good crosslinking characteristics. This product achieves dry films without thermoplasticity. DANCOLL_W155 is used as a paint-, finish- and coating binder as well as a dispersion for textile impregnation and textile equipment.

Application: DANCOLL_ W155 serves as a binder for paints, coatings, textile laminations and finishes. For the two component processing we are recommending the crosslinking with our aqueous crosslinker DANCURE 101. The tested applications of DANCOLL_ W155 are:

  • Textile impregnations and textile equipments
  • Ground- and top coatings for leather- and textile coating.
  • Leather binder blended with acrylate dispersion.
  • PVC finishes, printing inks and synthetic coatings finishes.
  • Mixings with DANCOLL_ 148-56 for textile finishes, especially for glazable
