Under low shear stirring for about 15 minutes to a paste. 3. Join required for the oil, stir the mixture evenly. 4. Adjusted to the desired viscosity with a solvent. 5. To avoid flake powder particles in the dispersion process and reduce curl and break the optical effect, the best selection of disc blade mixer or dispersing machine, the speed stir.
