CRAYVALLAC® REV

CRAYVALLAC® REV is a new high performance micronised amide wax rheology modifier offering perfect recoatability for regular, high solids and solvent-free coatings. CRAYVALLAC® REV has been designed to provide reliability and efficiency in a wide range of coatings. As other CRAYVALLAC® modifiers, it overcomes technical constraints such as seeding, false-body and migration of readily dissolved species to the surface. Even used in strong solvent systems, coatings formulated using CRAYVALLAC® REV offer an enhanced performance and very good recoatability.

Processing Information
  • The use of high-speed dispersers is ideal for the incorporation and activation of CRAYVALLAC® REV as they develop both the necessary level of shear and temperature.
  • CRAYVALLAC® REV is best added along with the initial charge of resin during the pigment dispersion and grinding stage.
  • Efficient activation will be achieved by allowing the temperature during dispersion to rise to 45 - 65°C (113 - 149°F), but more preferably from 55 - 65°C (131 -149°F), and maintaining this condition of dispersion and temperature for 20 - 30 minutes.
  • Note that the most suitable temperature highly depends on the formulation but that thanks to its robustness negligible differences are expected in the range from 50 to 70°C.
