REOLOGY ADDITIVES

Rheology additives can greatly enhance the application properties of diverse systems. However, custom solutions and accurate adjustment of the rheological profile are necessary for specific improvements. For instance, boosting storage stability demands a unique viscosity profile, unlike enhancing layer thicknesses. Moreover, enhancing viscosity in low shear ranges requires a different approach than improving brushing resistance.

Moreover, the additive must be precisely adapted to the polarity of the system, depending on whether the system in question is solvent-borne, solvent-free or aqueous.

ASTRA REO SERIES

Enhance Your Formulations with Precision

Rheology additives play a crucial role in the formulation of diverse systems, providing the ability to fine-tune their application properties for optimal performance. Whether you’re looking to improve the flow, stability, or texture of your product, our range of rheology modifiers offers custom solutions to meet your specific needs.

Customized Solutions for Every Application

No two formulations are the same. That’s why we believe in creating tailor-made solutions that address your unique requirements. For example, enhancing storage stability necessitates a particular viscosity profile that differs significantly from what’s required for boosting layer thickness or improving brushability. Our rheology additives are designed to deliver the precise performance characteristics you need, ensuring superior results every time.

Adapted to Every System

Understanding the chemistry of your system is essential for achieving the desired rheological behavior. Whether your formulation is solvent-borne, solvent-free, or aqueous, our additives are carefully adapted to match the polarity of your system. This compatibility ensures seamless integration and maximizes the performance benefits of your product.
