Compared to other hydrogenated castor oil-based rheology modifiers, CRAYVALLAC® SF is more tolerant to strong solvents and high processing temperatures due to the presence of its unique performance-enhancing amide. The activation process constitutes the conversion of the CRAYVALLAC® SF particles to an interacting network of fiber-like particles. It is this network that gives rise to the final coating’s shear-thinning rheology. This shear thinning characteristic 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. voir moins | Request Sample |
