Special features and benefits 

RHEOBYK-H 6500 VF considerably increases viscosity in the low shear range and thereby improves the sagging tendency and storage stability. The additive is liquid and therefore easy to handle. It is not necessary to specifically adjust the pH value or control the temperature during incorporation. When combined with rheology additives which are effective in the high shear range, such as the RHEOBYK-L/T series, it enables an optimum processability.
Recommended use
RHEOBYK-H 6500 VF is preferably used in emulsion paints that are based on acrylate, styrene acrylate, PVA and VAE binders.

Recommended levels
0.3-2% additive (as supplied) based upon the total formulation, depending on the properties of the formulation to be achieved.
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and processing instructions 
Addition under stirring ensures optimum distribution and the best possible effectiveness and reproducibility. RHEOBYK-H 6500 VF is suitable for adding to the millbase as well as to the letdown product, or as a post additive to retroactively adjust the rheological properties.
