Rheological additives

Arkema’s range of rheological additives CRAYVALLAC® provides coatings with excellent anti-settling and anti-sagging properties, while maintaining ease of application and good levelling thanks to their thixotropic behaviour. CRAYVALLACs® can be used in all types of coatings, whether in solvent, high solid or solvent-free systems.
