Calcined product, amino functionalized.
Aktifit PF 115 is hydrophobic and offers very low moisture content without increase under humid climatic conditions. According to the polarity of the PU the product shows moderate rheological activity (higher viscosity at low shear rates, yield point, shear thinning).
- excellent dispersion properties
- selectable rheology (free-flowing to non-sagging)
- easy processing
- good tensile strength and tear resistance
- good elasticity/compression set
- good abrasion resistance
- good chemical resistance, especially against acids
- good water resistance
- also suitable for food contact and drinking water applications (as per BfR and FDA regulations)
