Aktifit PF 115 in moisture-curing adhesives

1K PUR

Calcined product, alkyl functionalized.

According to the polarity of the PU Aktifit PF 115 shows moderate rheological activity (higher viscosity at low shear rates, yield point, shear thinning).

 

  • selectable rheology (free-flowing to non-sagging)
  • excellent strength of properties, up to 2-fold or 3-fold calcium carbonate (tensile strength and lap shear strength), mostly without reducing the ultimate elongation
  • good water resistance and chemical resistance
