How to Prevent Settling in Aqueous Coatings | Long-Term Suspension Stability

Learn how to prevent settling in aqueous coatings using high-thixotropy rheological additives for stable pigment suspension.

Settling in aqueous coatings leads to hard sediment, inconsistent color, and reduced shelf life. This problem is often caused by insufficient low-shear viscosity and weak internal structure.

Preventing settling requires maintaining a stable suspension network that keeps pigments and fillers evenly distributed. Inorganic rheological additives based on modified montmorillonite clay provide strong thixotropy and gel strength, effectively holding particles in suspension during storage.

By improving structural integrity at rest, these additives help maintain uniformity and reduce the need for re-dispersion.
