Alkyl functionalized based on Sillitin Z 86.
Aktisil PF 777 offers higher rheological activity (higher viscosity at low shear rates, yield point, greater shear thinning) and improved water resistance.
- 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)
