Micronised hydrogenated castor oil rheology modifier
Contact our experts
Product overview
CRAYVALLAC® PF is a modified micronised hydrogenated castor oil rheology modifier specially designed to facilitate the incorporation in powder form for better activation and easier handling. The activation process is the conversion of the CRAYVALLAC® PF fine particles to an interacting network of fibers. It is this network that gives rise to the final system’s shear thinning rheology. This shear-thinning behavior provides a very high viscosity under the low shear rates associated with sedimentation, and a low viscosity at the much higher application shear rates. The net result is excellent control of sedimentation combined with ease of application. CRAYVALLAC® PF is suitable for a multitude of applications.
