OPTIFLO-H 3300 VF

OPTIFLO-H 3300 VF is a VOC-free associative thickener that generates a slightly pseudoplastic flow behavior for aqueous systems. As a polyurethane solution, OPTIFLO-H 3300 VF increases viscosity in the low to medium shear range with an extremely low impact in the high shear range. This optimizes storage stability and provides an excellent balance between flow properties and the sagging tendency for various applications. OPTIFLO-H 3300 VF is liquid and easy to handle, not requiring pH value or temperature adjustments during incorporation. When combined with other rheology additives effective in high shear, it enables optimum processability. OPTIFLO-H 3300 VF is preferably used in emulsion systems based on acrylate, styrene acrylate and vinyl acetate binders. It is especially recommended for architectural and wood coatings where it helps provide the right viscosity and flow properties for smooth and even coverage without sagging or dripping.
