1K PUR
Calcined product, alkyl functionalized.
Aktifit PF 115 is applicable in 1K PUR adhesives.
According to the polarity of the PU the product 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
