CRAYVALLAC® MT

Arkema Rheology & Specialty Additives

CRAYVALLAC® MT is a micronised amide modified hydrogenated castor oil rheology modifier for solvent-based and solvent-free systems. CRAYVALLAC® MT is suited to systems based on aliphatic hydrocarbons, aromatic hydrocarbons and aromatic hydrocarbon/alcohol blends. Compared to the most basic hydrogenated castor oil based rheology modifiers, CRAYVALLAC® MT is more tolerant to stronger solvents. CRAYVALLAC® MT particles are converted upon activation into an interacting network of fibre like particles. This network 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.
