OPTIBENT-987 is a powdered rheology additive based on an activated, natural phyllosilicate. It produces a thixotropic flow behavior which improves the anti-sagging properties in pre-mixes without impairing hydration. OPTIBENT-987 increases the storage stability and reduces the settling tendency during application, enabling thick layers to be applied. It displays consistent rheological properties even at different temperature conditions. OPTIBENT-987 is suitable for aqueous systems in the neutral to alkaline pH range. It is especially effective in paste-like formulations where it improves stability and reduces settling. OPTIBENT-987 can be easily incorporated and provides long-lasting benefits.
