CRAYVALLAC® SUPER

CRAYVALLAC® SUPER is a high performance, micronised amide wax rheology modifier suitable for a wide range of solvent-based, high-solids and solvent-free applications. CRAYVALLAC® SUPER overcomes those difficulties which exist with hydrogenated castor oil based rheology modifiers e.g. seeding and false-body. Consequently, coatings formulated using CRAYVALLAC® SUPER exhibit an enhanced performance such as controlled flow behavior, ease of application and excellent sag resistanceIts smooth viscosity recovery will help to achieve high film thickness without compromising a good levelling.

Processing Information
  • CRAYVALLAC® SUPER is best incorporated and activated using a high-speed disperser.
  • It is usually best added along with the initial charge of resin during the pigment dispersion and grind stage.
  • Efficient activation will be achieved by allowing the temperature during this dispersion process to rise to 50 – 60°C (122- 140°F) depending on the coating system characteristics.
  • For the best results this condition of dispersion and temperature should be maintained for 15 – 30 minutes.
  • The use of high-speed dispersers is ideal in that they generate both the necessary shear and temperature required for full dispersion and activation.
  • The activation process constitutes the conversion of the CRAYVALLAC® SUPER particles to an interacting network of fibre-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.
  • Immediately following application, where low shear conditions again predominate, the coating’s viscosity undergoes a time dependent recovery as the network reestablishes itself.
  • This time dependence is known as thixotropy and enables the final coating to attain very good levelling.
