NM-ST 2641 Rheology Control Additive

Synthetic thickener

NM-ST 2641 Rheology Control Additive is a powdered synthetic thickener based on polyacrylic acid. Being used in aqueous systems for a variety of different purposes in printing, coating or other technical applications. It demonstrates efficient thickening performance and flexibility in formulation for different end-uses. This polymer is un-neutralized and requires addition of an appropriate neutralizing agent to achieve maximum thickening efficiency. Neutralized dispersions of the NM-ST 2641 show suitable viscosity and yield stress and can be used for suspending pigments or other particles in an aqueous system.
