Different additive classes and their special features

The use of rheology additives can significantly improve the application properties of a wide variety of systems. However, depending on the improvement aimed for, tailor-made solutions and an accurate adaptation of the rheology profile are necessary. Increasing storage stability, for example, requires a different viscosity profile than increasing coating thickness, while a different approach must be taken for increasing viscosity in low shear ranges than for increasing brush resistance.

In addition, the additive must be adapted precisely to the polarity of the system, depending on whether it is a solvent-borne, solvent-free or aqueous system.

This can be achieved through a variety of additive classes on different chemical bases.
