OPTIBENT are powdered rheology additives from BYK based on phyllosilicates that have been specially developed to meet the requirements of construction chemicals such as dry-mix mortars and paste systems. They make it possible to influence and control specific properties such as viscosity, yield point (stability) and workability. OPTIBENT additives are suitable for use in all mineral-based systems such as adhesives, mortars, plasters and screeds.
