Comparative Analysis of Leading Clay Types and Additives
Clay dispersion rheology optimization remains a dynamic focus for manufacturers and end-users seeking improved performance in paints, ceramics, construction, oilfield drilling, and personal care formulations. The comparative rheological behavior of key clay types—especially bentonite, kaolin, attapulgite, and hectorite—continues to inform additive selection and process design. In 2025, advancements are driven by both material science and the integration of sustainable practices.
Bentonite, particularly sodium-based varieties, remains a benchmark for high-swelling, high-viscosity dispersions, and is widely utilized in drilling fluids, foundry sands, and sealants. Companies such as Bentonite Performance Minerals and Imerys have introduced new grades with tailored particle size and surface modifications to enhance thixotropy and anti-settling behavior, allowing for lower dosages and better pumpability. Kaolin clays, on the other hand, are valued for their plate-like morphology and moderate thickening, with KaMin LLC offering high-purity, calcined variants that deliver improved suspension stability in waterborne coatings.
Attapulgite and hectorite, both fibrous and layered in structure, are gaining attention for their unique rheological profiles—exhibiting excellent suspending capacities at low concentrations and good salt tolerance. BASF markets attapulgite-based additives for paints and industrial fluids, capitalizing on their rapid viscosity recovery after shear. For personal care and specialty applications, Elementis has expanded its hectorite product lines, promoting controlled gel strength and clarity in transparent gels.
Additive innovation is central to clay dispersion optimization. Polyacrylates, cellulose ethers, and biopolymers such as xanthan gum are routinely blended with clays to tune yield stress, flow curves, and storage stability. Recent launches by Ashland and Dow feature multifunctional rheology modifiers that enhance dispersion homogeneity and compatibility with pigments or electrolytes.
