CRAYVALLAC® OPTIMA

CRAYVALLAC® OPTIMA is a high performance, micronised amide wax rheology modifier suitable for high-solids and solvent-free applications recommended for its ease of activation and smooth viscosity recovery (good levelling). CRAYVALLAC® OPTIMA overcomes those difficulties which exist with hydrogenated castor oil based rheology modifiers e.g. seeding and false-body without the need of increasing the temperature of activation. Its smooth viscosity recovery will help to achieve high film thickness without compromising a good levelling.

Processing Information
  • The use of high-speed dispersers is ideal for the incorporation and activation of CRAYVALLAC® OPTIMA in that they develop both the necessary level of shear and temperature. CRAYVALLAC® OPTIMA is 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 dispersion to rise to 40 - 70°C (104 - 158°F), but more preferably from 55 - 65°C (131 -149°F), and maintaining this condition of dispersion and temperature for 20 - 30 minutes.
