Rheological additives in paints and coatings and their role in the formulation of paints and coatings

Rheological additives play a crucial role in the formulation of paints and coatings by controlling and modifying the rheological properties of these substances, as well as adjusting viscosity, thickness level, and thixotropic behavior.

These additives enhance the viscosity of paints and coatings, which is valuable for controlling consistency and thickness level, enabling a more even application and preventing the settling of solid particles present in the formulation. Additionally, they improve resistance to dripping and sagging, which is particularly important in vertical applications.

In the industrial realm, the incorporation of clays, sepiolites, and attapulgites as rheological additives in paints and coatings (both water-based and solvent-based) offers a range of key advantages:

Viscosity Adjustment: These additives provide the ability to modulate the viscosity of paints and coatings, simplifying their application and granting more precise control over coating thickness.

Enhanced Applicability: Thixotropic additives derived from sepiolites and attapulgites improve the dispersion and flow of paints, enabling a uniform and smooth application on a wide variety of surfaces.

Sedimentation Prevention: Thickeners derived from these minerals act as guardians, preventing the settling of solid particles in the paint or coating, ensuring a homogeneous mixture and prolonging the product's shelf life.

Drip Resistance: Rheological additives originating from sepiolites and attapulgites act as shields against dripping and excessive flow of paints and coatings. This feature is especially beneficial in vertical or inclined surface applications.
