STP-E / STP-U
Calcined product, amino functionalized.
Aktifit PF 115 offers highest lap shear strength in STP-U.
- 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
