RHEOBYK H 7500 VF is a VOC-free associative thickener (HEUR) for aqueous systems, designed to create highly pseudoplastic flow behavior, particularly suited for spray applications. It is ideal for wood coatings and compatible with wood surfaces. The product offers excellent processability, storage stability, and high sagging resistance. RHEOBYK H 7500 VF is composed of polyurethanes (PU) and is compatible with acrylates and vinyl acetate-ethylene copolymer (VAE). It complies with Clean Air Act (CAA) regulations and certifications under SARA 302, SARA 313, SARA 304, and CERCLA. This liquid product is easy to handle and provides excellent pseudoplastic rheology.

Special features and benefits
RHEOBYK-H 7500 VF significantly increases the viscosity in the low shear range. It reduces sagging and increases storage stability. The additive is liquid and therefore easy to handle. It is not necessary to 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 7500 VF has been specifically developed for emulsion paints that are based on VAE binders. It can also be used in emulsion paints and coatings which are based on acrylate, styrene acrylate and vinyl acetate.

Recommended levels
0.3-1.25% additive (as supplied) based upon the total formulation, depending on the properties of the formulation to be achieved. In exceptional cases, the dosage can be increased to 2%.
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 7500 VF is suitable for adding to the millbase, to the letdown product, or as a post additive to retroactively adjust the rheological properties.
