OPTIBENT-MF

Powdered rheology additive based on an untreated, natural phyllosilicate for aqueous, mineral-based construction systems. OPTIBENT-MF generates thixotropic flow behaviour and is particularly well suited to free-flowing systems with low viscosity hysteresis. It prevents the tendency of aggregates to sediment and bleed, without overly impacting the leveling properties. At high levels, OPTIBENT-MF can also reduce the water absorption of mineral binder systems as a result of its morphology. OPTIBENT-MF is suitable for a variety of aqueous construction systems.
