Special Features and Benefifits
OPTIBENT-987 produces a thixotropic flflow behavior. It improves the anti-sagging properties in pre-mix mortars
and their ease of processing without impairing the cement hydration. In aqueous paste-like binder systems,
OPTIBENT-987 increases the storage stability and reduces the settling tendency during application which enables
thick layers.
OPTIBENT-987 also displays consistent rheological properties even at different temperature conditions.
