CRAYVALLAC® PA5 XSR 25

Arkema Rheology & Specialty Additives

CRAYVALLAC® PA5 XSR 25 is a pre-activated amide wax dispersed in xylene. CRAYVALLAC® PA5 XSR 25 is an alcohol-free version of polyamide paste, such as PA3 X 20, with an enhanced robustness to extended high-speed dispersion. It is a rheology modifier in paste form for solvent-based industrial coatings, industrial wood finishes, protective, and marine coatings. The use of CRAYVALLAC® PA5 XSR 25 provides a very simple and direct means of introducing shear-thinning rheology with thixotropic viscosity recovery to coating formulations. CRAYVALLAC® PA5 XSR 25 is a pre-activated amide paste and exists in the form of crystalline fibres. In a coating system, these fibres form an interacting network. It is this fibrous network that gives rise to the shear-thinning rheology of the final coating.
