Rheobyk-H 3300 VF (formerly OPTIFLO-H 3300 VF)

VOC-free associative thickener (HEUR) for aqueous systems to generate a slightly pseudoplastic flow behaviour. Rheobyk-H 3300 VF (formerly OPTIFLO-H 3300 VF) increases the viscosity in the low to medium shear range with an extremely low impact in the high shear range.

It optimises storage stability and provides an excellent balance between flow properties and sagging tendency. 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.

Rheobyk-H 3300 VF is preferably used in emulsion paints and coatings that are based on acrylate, styrene acrylate and vinyl acetate binders as well as in PU and alkyd emulsions, and epoxy dispersions.

Recommended for architectural, wood and furniture coatings.
