RHEOBYK T 1000-VF is a VOC-free associative thickener that increases viscosity in the high shear range with extremely low impact in the low shear range. It contains 22.5% active substance and is an aqueous solution of a polyurethane. RHEOBYK T 1000-VF improves processability, leveling, and storage stability. It reduces spattering during application and allows for greater layer thicknesses to be achieved with excellent balance between flow properties and stability. RHEOBYK T 1000-VF enables adjustment of a flat rheology profile across a broad shear range. It prevents the introduction of air and tearing of the flow curtain, enabling increased coating speeds.
