Rheology is the science that studies the behavior of deformable materials under the influence of applied forces. It focuses on the analysis of the flow and deformation properties of substances such as paints, coatings, building materials, chemicals, drilling fluids, etc.
Thixotropy is a rheological property of certain materials that exhibit changes in their viscosity or fluidity in response to the application of stresses. It is characterized by a decrease in viscosity when subjected to agitation or shearing and a gradual increase in viscosity when left at rest. It is a desirable property in many products and applications, as it allows for easy application and extension of the material when agitated or force is applied, but ensures greater stability and resistance to flow once at rest.
Sepiolite is a naturally occurring fibrous mineral belonging to the group of clays – phyllosilicates. It is characterized by its structure in the form of needles or fibers, which give it unique properties. Sepiolite is extracted from natural deposits and is used in various industrial applications due to its exceptional rheological and physical properties.
Sepiolite rheological additives, thanks to their exceptional pseudoplasticity, thixotropy and ability to increase viscosity, improve the workability, stability and efficacy of formulations in a wide range of industrial applications.
Sepiolite is known for its thixotropic property, which means that its viscosity decreases under agitation or shear stress and recovers when agitation ceases. This makes it easier to apply and disperse the materials.
These additives help prevent the sedimentation of solid particles in the formulation, maintaining the homogeneity and stability of the product over time.
Sepiolite-based rheology additives improve the cohesion of mixtures, reducing dripping and runoff, especially in vertical applications.
These additives are versatile and can be used in different formulations and systems, giving formulators flexibility to achieve desired properties.
Attapulgite is another naturally occurring clay mineral that is widely used in industry as a rheological additive. It is characterized by its needle-like structure, which gives it unique properties in terms of rheology and water absorption. Attapulgite-based rheology additives are used to improve flow and viscosity properties in a variety of industrial applications:
Attapulgite has a high water absorption capacity, which contributes to its thixotropic property. This means that the viscosity decreases under shear stress, such as agitation, and increases again when the stress ceases, improving applicability.
These additives help prevent the segregation and sedimentation of solid particles in formulations, maintaining the homogeneity and stability of the products over time.
Attapulgite rheology additives offer easy dispersion and great versatility. They offer a high thickening capacity while improving workability, stability and efficiency in a multitude of applications.
These additives facilitate workability and allow a uniform and smooth application of the products where they are added.
Attapulgite-based rheology additives are compatible with a variety of systems and formulations, allowing them to be adapted to different requirements.
